AIBU to refuse a friend £4k without knowing what it is for?

[rainershine22]

My friend asked me to borrow a large sum of money. (£4k).

He wouldn't say what it is for, but claimed he can't get help anywhere else (such as banks/loans etc...) which is obviously already a red flag.

I asked if everything was ok in his life and what was going on... but he didn't want to divulge too much and was just said he had 'cashflow issues'. I know his two children and he alluded to it being something related to them - but not much more...?!

I declined to give him anything/said no - but he's messaged again today AM asking me to reconsider. He clearly sounds desperate, but AIBU in still saying no?

My cars been broke, my home isn’t the best but I’d never ever ask anyone for 4,000 like what on earth. No you are not being unreasonable he is for asking

No repayment plan mentioned- sounds like asking for a gift not a loan.

Don’t do it. Either give him the money with a smile and never mention it again, or just say NO. Lending money to friends and family is fraught with difficulty and rarely ends well.
