Is it normal to like a teacher?
Yep.Totally normal
Yes, it’s normal to have a crush on a teacher. Feelings can happen; what matters is keeping appropriate boundaries, especially if they’re currently teaching you.
A teacher can seem especially appealing because you admire them, spend time around them, or like the attention and encouragement they give you. Lots of people have had a school crush, and it doesn’t mean you’ve done anything wrong.
You don’t have to act on it. If they’re your current teacher, keep things professional: they’re in a position of authority, and it’s their responsibility to maintain clear boundaries too.
