A Mumsnet user has united the internet over her reaction to her MIL's unusual request.It’s all kicking off on Mumsnet. This week a parent took to the site to ask if she was being unreasonable for refusing to let her mother-in-law “bring her own kettle when she visits”.Mumsnet user BiscuitHammer admitted it was a bit “silly” but noted the dilemma was “causing actual rows”.She explained her mother-in-law is set to visit and has said she will be bringing her own kettle because the water from theirs “tastes funny”.“I genuinely don’t know what that even means?? It’s just a normal Breville one from Argos,” said the bemused parent. “She says she can ‘taste the plastic’ and it ‘ruins tea’ which is ridiculous because we’ve had it over a year and no one else has ever complained.“I told her she’s being dramatic and she got in a strop. DH [dear husband] is now saying I should just let her bring it to keep the peace
