Very true, there will be party popper in every family and it's annoying when they ruin the fun moments of other family members. I don't think they even know that their actions always deprive others to have fun because if only they knew, then I think they will be considerate.

Your uncle was such a tough one, at least he would have just pretended and joined the celebration for once. Why on earth did he even followed his wife and daughter in the first place if he knew he wasn't going to join the sitting.

Well, it's a good thing you and the rest of the family managed to complete the outing before departing.
