Think it's quite amusing, but I would not dream of doing it - I would probably get in touch with someone even odder than me!

Social media is awash with the latest fad...contacting your text door neighbour...yes, you read that correctly.
It was all the rage years ago and has recently resurfaced.
People have been sending texts introducing themselves to the phone number the same as their own with just the last number altered to one less or one more eg: a text from your number (hypothetically 07787 998231) would be sent to 07787 998230 or 998232.
Have any GNs received one of these unexpected 'calling cards'?
Some of the responses are, IMO, quite funny including the one I screenshot.
Definitely not for those who've had their humour lobotomised. 
No mobile phone, so no problems 
Snowflakes? ❄️❄️❄️.
Or people with more to interest/engage/amuse them? More in their lives?
I tend to be sceptical of people who tell me “such and such” is “the latest fad” or that social media is “awash with it”
I haven’t seen any evidence anywhere and even if I did, it sounds totally uninteresting.
Why on earth would I want to do this? “Oh what a hoot! “
Really? 
No. Not the same thing at all.
Supposed to be friendly calls, not selling merchandise or anything else nor scams.
You obviously don't know the person you ring and I think the point is to introduce yourself, say 'hi/hello' and possibly start a conversation.
The fact that it's random makes it popular.
One man contacted his text door neighbour and the person who answered asked who he was. The texter text his name and asked who the other man was.
The second man said he was Barack Obama...but here's the texts they sent.
I actually think it's really funny.
