Has anyone else done anything as daft as this?

In my early days as a TA some years ago, the teacher explained to the pupils that they needed to measure 150ml of liquid.
My charge and I looked at the equipment. The 150ml tubes were all in use so we waited until other pupils had completed the experiment.
The teacher asked what we were waiting for. I explained the issue. He looked me in the eye and said, “perhaps you could use two 100ml tubes?”
I don’t think I’ve ever felt more embarrassed. Before or since.

Fallingsrar I once got into the wrong car. Same make and colour as ours with a gentleman sitting waiting in the driver's seat. He looked startled when I landed on the seat next to him!

Nearly done that twice. I've done loads of the stuff on and off...above (just not leaving the pram), and think Fallingstar what nice neighbours. Nosy, but kind.

Life is more interesting this way. 😊

It depends how old you are, too. With white hair and a pleasant smile people usually smile back and are helpful. No point trying to be other than you are.

Laughed out loud at a couple of these! Yes we all do strange and wonderful things sometimes! It can make life interesting also!

Dh and I had tickets for a concert at the Festival Hall. Arrived in plenty of time, but had trouble finding the correct auditorium. (For anyone unfamiliar, it’s a huge venue.) We once thought we’d found it, but there was evidently a rehearsal going on.

Eventually we asked a couple of staff, who looked at our tickets.

Er, right date, wrong year!! We were a whole year early!
We had to laugh, too.
Had a drink on the balcony overlooking the river, a riverside walk, and headed home.

EkwaNimity I did that when I was in my 40's. On the bus returning home after work I looked in the direction of my usual car park and I remembered....I had gone to work in my car!!!

Yep, done exactly the same - but in my twenties, so no excuse!

I nipped to the shops in the car one day, left the car in car park behind shops, walked home, then realised I had left the car, so had to walk back to where I left it. but of course there was a neighbor sitting on his front step ,shouted over as I went passed
did you forget to bring the car home.

One dark winter morning, in a rush to get to work, I put on a pair of shoes, dashed into car and drove to work.

Once arrived I realised, one was black, one was navy and they had quite different height heels. Most people noticed and commented and it was quite odd when walking 🥱

I did this with navy court shoes from M&S, identical, but with different heel heights.
I thought I had had a stroke!

I was merrily (ha ha) mowing the lawn on Friday and musing about what to have for tea when I suddenly thought “ Gosh it’s Friday!” I was supposed to take my car for its M.O.T. on Friday morning! Luckily they were able to rebook it for Monday and it isn’t due until Tuesday. I am going to drive it up tonight and put the keys through the letterbox.

Oh Gwyllt, I had to laugh! That’s worse than forgetting a car. Good job you didn’t live in the States, probably worth a prison sentence, well it would now!b

I think I was wearing the other pair!

Didn't really notice until a sharp-eyed colleague pointed it out.

Many years ago, before strict legislation was brought in, all the taxis in our town were all old rust buckets. I once booked a taxi and asked it to wait outside my workplace. I jumped in the back and gave the driver my address. The driver looked at me horrified as it was a private car!

About 20 years ago I was in Marks and Spencer when I spotted a lady I knew. The lady had her back to me so I gently tapped her shoulder and said 'hello Maude'. The smiling lady turned to face me . She wasn't the lady I knew but she said 'we don't know each other, but my name is Maude '.

Went to choir last night but another event was taking place at the venue we use. Decided it wasn't on because our concert was on last week and choir leader must be having a break. Went to art class this morning - nobody there. Checked my phone and discovered it was Wednesday not Thursday - choir tonight, art tomorrow.
