you know when he or she doesn't want to associate with you or every time you raise your hand and doesn't call on you.My advice live each day like U don't care,work hard on every project and eventually you'll win his or her heart
If the teacher is constantly getting on you for something that other people are doing to then you knoew they don't like you! also if you are constantly getting blamed for something you didn't do then just don't fight back mention that you didn't do it and if they continue to say you lie then try to come up with some proof if there is none just drop it and except the punishment just next time try and get proof!
Ask them.
You get to know the person!
warn the person you like
The brain will know if you like someone or not. Your instances tells your brain.
In my opinion, you start to like someone when you get to know them. Usually you like someone because of their personality. It comes naturally when you start liking someone. It can be when your young, or old, it doesn't matter. You'll know you like someone when you start being more nervous around them then usual. It helps if you know they like you too.
You can have a crush or be infatuated from afar with someone you don't know or even may know a little but when you feel you like someone you will like them as an individual and know them.
ask them. or get someone you know to ask them
If you want to be with them
Love at first sight
Ask him, get to know him better!
talk to them get to know them better
A crush develops when you may see someone you like, meet someone but don't know them or know them but shy..........it is an object of our infatuation.
