So found a text from my mum this morning saying thank you for one of the hug in your pocket gifts signed from my 2 children, one a toddler and the other a newborn. I didn't send the gift and checked with all my close family who didn't send it either. Now I've discovered it was from an old colleague of my mum's who has never met my children or myself and I am just feeling pretty annoyed somebody would think to send something like that, personalise it and sign it from my children. Aibu?
