When my oldest daughter was 6, we lived in a neighborhood full of young kids of all ages, and luckily there was a group of 7 girls in her age range. Any birthday list was basically already made, nothing to think about. Or so I thought. Then it happened. My daughter was not invited to a birthday party of one of the group. She was upset. I was devastated. Although my daughter doesn’t remember this event, I have never, will never, forget. Call me petty. Although the girls were not the closest of the group they were friendly and it was certainly noticeable that my daughter was left out. I did not ask the mom why and maybe there was a legitimate reason although I can’t fathom what that could have been. So on the topic of “do you invite the whole” my opinion is yes if it would be awkward otherwise. If you are inviting 15 of the 16 boys in a class suck it up and invite the 16th. Do you agree or disagree? Please comment below.
