When my mother texts me, pretty much every sentence ends in an exclamation point.
We had this conversation a while back:
[A few back and forth texts regarding a car issue I had]
Me: Bro-in-law brought the car back to my house.
Mum: Did he charge you?!
Me: Big Sis#2 said not to worry about it.
Mum: Then don't!
Me: Lol why are you yelling?
Mum: When was I yelling?!
Me: The exclamation points make me read it in a yelling voice.
Mum: Then you're the one yelling!
I shall just have to add this to the long long list of things Mum cannot understand because she refuses to do so.
