That basically. We were at a shopping centre DS was in the pram two young boys around early 20's walked passed saw DS in pram, laughed and said "definitely not yours mate". I'm white, DP is black and DS is fairly pale in the face but the spit of DP. We have always had jokey comments from close family/friends and DP seems to think this is just the same and it's hilarious. AIBU to be a bit offended? And to wonder who the hell does that to a stranger in public?!
