If they're sexually active. How big their cup size is and what they're doing after school.
LMAO! OH my!!
I as a parent have not liked:
Teacher discussing her boyfriend with the class.
Teacher giving deragatory silly awards
asking questions, that would indicate that their home life was less than acceptable.
Ones that require A.,B.,C. or D.none of the above answers
basically anything in their personal life that doesnt have a reason behind asking it (like if a kid was being abused at home, or anything like that)
eh I can see how that can be taken an invasion of personal boundaries but some teachers are like that because some want to be friends with their students like "oh what did you do over break?" or "oh how was that concert I heard you talk about" but if they continuously give off a bad vibe and those questions get more and more private then thats when it goes overbaord
How much money do your parents make?
