What hints will your best guy friend make towards you if he likes you?

okay... i am in grade 10 but when i was in grade 9 i had a guy friend and he liked me as i liked him as well..

How they act: they start to talk to you more yet they often annoy you. they some times blush when they are trying to talk but mess up. they try to spend more time with you. they some times start to hug you after a wile and eventually they ask you out and that can lead to kiss and more...
