Once, ages ago, but badly. Felt very sorry for a boyfriend of a dd, whose parents (so he said) had rejected him. Gave him a substantial amount of cash in order to enable him to start the further education course he wanted to do.,
Not long afterwards, my idiot dd let him drive my car (she was allowed to) whereupon he pranged it, laid into the other party, and was charged with ABH.
Idiot that I was, I arranged an initial meeting with a solicitor for him - he didn’t show up.
So I went to his flat - no reply. Since he’d hinted at suicide to dd, I thought the worst, seriously panicked and called the police.
They managed to open the door - he wasn’t there. (The police were very kind and understanding.).
When I eventually managed to contact him (pre mobile phones) he simply told me, quite unconcerned, that he’d forgotten.
That was absolutely It as far as I was concerned, but only after he’d pursued dd to the university where she’d just started, and tried to break her (hall of residence) door down, did she finally finish with him. After that, the mere mention of his name would make her shudder.
