when my dad died my sister and I were asked by mum to clear out his things as she couldn't face seeing them every day..it was like a sword through her heart she said ..poor soul.
We found all manner of strange things ,the receipt for a new kitchen that to our knowledge was never fitted ,a huge number of brand new clothes still with tags that he'd had as gifts and never used and loads of things that made us giggle.Always good when you're grieving.
The strangest was a piece of string with a knot in it ,inside his wallet.Must have been to remind him of something ,we'll never know what or if he did it or bought it ,I wish he'd just written a note to himself.It made us speculate for ages ...always with a smile .
