DP's cousin (in her 30's) always asks my children who are aged 2 and 4 to kiss her DD who is 2 goodbye. She's quite insistent and will say repeatedly 'Kiss xxx goodbye' and when they don't she'll say 'come on xx give xx a kiss goodbye' I think she asks them to kiss her DD goodbye because they're older, albeit only by months. I always try to make light of it and say they don't really like kissing goodbye but she always pushes! Every time! and then gets stroppy because they won't. Why do people do this? I won't force my children to kiss people goodbye if they don't want to.
