AIBU to be annoyed because my MIL is ill

[bubbleOseven]

we were supposed to be going to my MIL for lunch on sunday but she has cancelled because she is ill.

Weirdly, she is always ill when we are going to hers for lunch although never ill when one of her 3 dils are taking their turn to cook lunch.

She just doesn't want to do it does she?

Any chance she really is ill - what's wrong with her?

A bad cold she said

Oh - I think she maybe doesn't want to cook you dinner then

I'm a (sort of) mil
I was ill last Sunday but still cooked lunch for Ds and his GF
After lunch DS and GF watched TV for a couple of hours and then said
'Thanks for lunch.....byeee'
Didn't offer to wash up.
They never cook lunch for us
F**k 'em
Shan't ask again for ages....[grrrr]
