PIL are visiting for the weekend. Don't mind, get on well with them as a general rule, but MIL is DOING MY HEAD IN! I'm 30 weeks pregnant and have had about 3 hours sleep so I'm well aware I may be BU, but ALL morning she has been singing random things in a comedy off-key voice. I mean ALL morning. I don't know if she even realises she's doing it. Sometimes it's nursery rhymes, sometimes random lyrics, sometimes just a commentary of whatever she can see. I've had to come upstairs out of the way before I get my hands round her neck!
AIBU, just hormonal and tired, or perfectly reasonable?
