I am a bit 
that after briefly chatting to another Mum at a party a couple of weeks ago, which must have been the 3rd convo I had with her in 2 yrs, she has personally emailed me and asked me to sponsor her for a biking event.
Our children were at nursery, never played together but she was someone I said hello to at the gates. It's not even a general group mail but a personal one asking me to sponsor her. I have looked at the offering everyone has given and it's all £20 and I am totally skint at the new term forking out for activities again etc. It is v likely I will see her again at a party/ dance class or whatever.
WWYD?
