Friday, I had specialty class, my teacher called me “good little girl” while I showed my classmate photos of what I had cooked the Wednesday before this Friday.
So I guess he saw my phone screen and heard some pieces of our conversation (this happened during a short break he had given us during inter-class.

I'm embarrassed about going to class tomorrow since I start with 2 hours of practical work with him.

Am I exaggerating or is this something that ppl aren’t supposed to say?

Note that I am shy by nature so it is probably me who is extrapolating.
