Hate doing this! Friend C had some good news, so friend B asked if I wanted to get something for C. B got busy so didn't sort anything so I sorted a gift and asked if she liked it and would be happy to go halves - she agreed, a week ago.
I got round to buying said gift yday and emailed her, no response, fine as she has been busy. Gift has arrived and we have been thanked. I don't want to chase but equally the money would be handy (£35 each), how long do I leave to ask?
