Have arranged to meet a friend for drinks/meal tonight.
I've just got back from an overnight work trip, which has involved 4 hours travelling yesterday and today, 2 early starts and less than 6 hours sleep the last 2 nights. I am shattered. All I really want to do right now is go for a doze on the sofa.
But I feel bad for letting my friend down. She's recently separated but hasn't told any of our wider group of friends other than me. That said although she had invited another couple of friends out tonight, I don't think either of them were free. So if I say I'm not coming, she either won't be going out at all, or not with anyone she can talk openly to.
How bad would it be of me to cancel?
