Oh, reading this thread has reminded me of something that I think I'd blocked out of my memory!
It was many years ago now, when I was 18 (he was older) we met in a club then met for a date the next day in a cafe, he seemed great.
2 days later he messages me one evening & I was out so I said that we could meet when I got back, he was waiting outside my flat & he had some kind of a metal box in his hand. On questioning him, he said 'Oh it's a toolbox, I got here early & that car across the road was open so I took it from there'... I wasn't sure if he was joking! He kept laughing & I told him to go & put it back, if it was true, but he kept saying that it was fine & not to worry. I said 'If you've really stollen that then it's not 'fine' & he said 'Honestly, I promise that it's fine'. I was so confused but went along with it...
Anyway he left a few hours later & he said 'You can keep that' & left the toolbox with me!
I didn't see him again, I couldn't really work out what had happened with the toolbox but I had a bad feeling about it.
I didn't know what to do with it, I remember for a few days after, standing outside my flat looking at the houses & cars opposite & thinking 'I don't even know which one, so I can't even try to give it back, & if I do, then I'll get the blame won't I' (I didn't know his surname or where he lived)
I kept hold of it for 6 months (to the day! In case the police came & asked for it) then I shoved it in about 20 bin liners & put it at the bottom of my black bin.
I feel terrible writing that now
