How would you feel if your mom suddenly becomes your homeroom teacher?

Hello,

I want to ask. You’re a teenager and new in town with your parents. You’re about to attend your first day at school and suddenly gets shocked to see your mom introducing herself as your new homeroom teacher.

How would you feel about this? Would you be happy that your mom is there for you even in school or would you rather not tell any of your new friends and keep it a secret unless the mom reveals it herself during introduction?

I want to make it clear that I’m asking about mom becoming teacher not dad. “You” can be a teenager, either male or female.

Regards
