On my facebook list I have an old friend who I've not really been in touch with for a few years.
I've just had the following message from her:
Hi would love to catch up with you. Maybe we can meet next time you're down in London. I've got a business proposition for you and your dp too - me and my boyfriend have started up a new company and we're looking for about £5k investment. Thought it would be right up your street. Can't wait to see you.
So after about 4 years of not contacting us she suddenly pops up and asks us for £5k!
AIBU to just ignore her and most likely unfriend her.
