Student used their mom's phone to yell at me over text for their final grade... 2 weeks after school ended.

I use google voice as a way of communicating with parents over text. A student who didn't do well in my class used their mom's phone (who I had talked to earlier this year) to text me asking me if it "was possible" to raise "my kid's" grade.

Couple of things. One, I know it's the kid using their mom's phone because the way the text was written changed from one text in April to another, now. Also it called me bruh. Two, I submitted grades 3 weeks ago. And three, it is SUMMER. I'm off the clock lol.

I didn't answer but now I'm wondering if I should use a different method next year if I'm going to communicate with parents.
