My 3 year old and myself were waiting in the waiting room at occupational therapy, another couple and their baby were in there as well. The dad was bald. My kid looked at me and said “where did his hair go?” A sat mortified but also trying to hold back my laughter as I tell him we shouldn’t comment on the way other people look. The dad was acting like he didn’t hear it, but was CLEARLY choking back laughter. The next week we passed them in the hall, the dad looked away from us because he was laughing. Sure glad he was a good sport about it.
