it might be he wants to know if you like someone or you might have a crush on him
Either teacher know
We don't know. You should ask your crush to explain it to you.
crush means when your in love just another word for in love sometimes crush can mean the person they/your like doesn't know (2) 'crush' is quite different from 'love' or 'being in love' -when you have a crush on someone or someone is your crush it means you know from the outset that there is little likelihoood of an ongoing relationship, that there is no reason for thinking your feelings are reciprocated. For example, you might have a crush on someone you see now and again at a bus-stop but have never spoken with, or on a new teacher. The main difference between a crush and love is that a crush is entirely a one-way affair with the crushee usually totally oblivious of the crusher's interest.
It sounds like something other than a crush. If you had a crush on someone, you'd know exactly! who it was. There are lots of emotions it could be: perhaps anxiety or depression.
It means that your crush noticed you, and wants to talk to you but might not know what exactly to say.
crush
they want to know whats up
if he is being mean or hurtful towards you (usually)
It means that he/she had crush on you when they didn;t even know yyou, and have just seen you. It's pretty self explanitory.
When a teacher you know says hi to you it means they are being polite and acknowledging you.
1. your crush didnt know it 2. your crush is trying to learn something new or more about you 3. you still dont know if they are "interested" or just filing a restraining order.
