Listen To The Kid, Genius
Being a kid is hard. It’s even harder when you are sharing new knowledge that is fresh in your brain, only to have someone older than you tell you that you are wrong. Such was the exchange that this poster had with a neighbor’s kids. The kid shared an exciting bit of information with this person, and her reaction is just… sad. Bats are mammals, friends.
It seems as though the neighbor kids’ parents are doing a fine job of educating their children. But we can not say that the OP received a decent education in school, and from the impression left from this post, probably not at home, either.
