It was a ‘big’ birthday for paternal grandparent. Grandparent likes to make a fuss of others on special occasions so is definitely a card and present type of person however her son is a self confessed ‘not a card person’.
Would you expect child’s father to supply a card and present for his child to give to his mother?
Or is it the job of the primary care giver to supply a card and present in case nothing was organised?
