I have an impending visit from my MIL - she visits every 3 months or so. I have cleaned, tidied and even gardened for the visit. She voices her opinion on everything - me, my clothes, my hair, the children, the house: and points out anything which does not come up to scratch. We need a new kitchen, so she's bringing along some brochures to go through with me.... She also freely goes upstairs and has a look round - no need we have a downstairs loo. Hence upstairs is looking it's neatest, since she last visited. I work from home, and am extremely busy, so don't appreciate this busy body coming and telling me what needs to be done around the place. Any tips on how to get through the visit would be appreciated. AIBU to hide in my study while she's here?
