I went into work today despite feeling manky, which I think was very admirable
(I'm not contagious!)
went to late work meeting this evening and contributed to discussions etc, wasn't useless I don't think, but felt headachey and manky
am supposed to be going out for dinner and drinks now, at a pub very near my house
I mentioned that I wasn't feeling 100% and might just go home, but my boss said they would really like me there and would I change my mind and come out for dinner
and it is VERY nice to be wanted, because I haven't always felt all that valued at work - I have felt bad at not being included in the past, and now I am definitely invited and I don't want to go 
I have popped home to change (pub is very near my house) and said I may join them, if I feel up to it
I don't want to be an ungrateful git and rain on their parade, but on the other hand they will have a nice time whether I am there or not and I really don't feel great
AIBU to text my boss and say sorry for party pooping but I just want ibuprofen and sleep? Or should I stop being such a minny-pinny and go and have dinner?
