Well? Am I?
I've almost given up hope of seeing that money again. Apparently, the money he and SIL were going to pay me back with is "tied up in shareholder based trust funds", which apparently, the people who the shares are with, are refusing to pay out 
Anyway, It's DB's birthday in 2 weeks. When asked what he wanted for his birthday, SIL said he's asking everyone for money? WIBU to say I would have given him £50, but he can take it off what him and SIL owe me?
