I grew up in an age where parties for birthdays were small, intimate affairs with only family and maybe a few close friends, so we'd always open our birthday presents with everyone there to see our reaction, just like at Christmas, baby showers, or bridal showers. The only time we didn't open gifts in front of guests was at a wedding.
Nowadays, though, birthday parties seem to be big, crazy events with dozens of kids invited and the gifts tend to be piled up in one area to be opened by the birthday boy or girl after everyone has gone home. This seems really weird to me, but I'm hearing more and more people say that it's rude to open presents in front of the givers.
Is it because they're no longer intimate affairs and are so large like a wedding that so many have made this shift? Do you think it's rude to open gifts in front of your guests?
