MIL is a lovely women really, but positively enjoys being frugal and detests any excess in all its forms.
She's baked us a lovely cake, but is determined for it to last for as long as possible. She is the master slice cutter and won't let anyone else near it.
AIBU to be a bit disappointed with the size of this slice?
