I've noticed this peculiar tendency with teachers to use a lot of exclamation points in their emails. For example, from Mrs. Jones:

Hi!!! I just got back from teaching in Abilene last week. It had some
very nice teachers but I don't really think that I would enjoy living in
Abilene!!! [...] Please reply when you get this message so that I don't have to call you!!!
I hope that your summer has started out well!

Mrs. Carney does the same thing too.
