I'm a regular but have namechanged because some friends in RL know my posting name.
A friend/acquaintance of mine has emailed asking if I can help look after her children next week because she has to go into hospital and her dp doesn't get home from work until late.
I could juggle things around to help but I'm up against it for work deadlines (would have to take time off work at v short notice) and I'd have to see if the childminder could do (and pay for) an extra hour and a half at the end of the day because dd's normal pick up time is right in the middle of when I'd be needed and it's across town so would take me 20 mins at least to get there.
I have said sorry but no I can't help but I'm feeling really guilty. I'm trying to justify my position because i suspect her dp could take the time off work but I still feel mean 
AIBU?
