Forget it

Ok, I met him again today, but I really got no idea how would that happen!
So in the morning before the first session started, I teased my friend, that he had a crush on a beautiful girl from another school, but then he teased me back. He wanted to say to my old friend ('A'), that I had a crush on him!
Oh my! I thought first that he just kidding, but he actually did it. He said to my old friend "Hey, she's there!"
DAMN IT!
During the breaktime, he teased me again. He dragged 'A' to me. First I thought 'A' will really angry at him, but he just smiled, so maybe my guess was wrong. I always thought that he wouldn't speak to me, but actually he spoke to me!
Unfortunately, my class already started again after the break and I was late! I wanted to come in but I was so afraid, but he said "There's no teacher inside"
So I just came in without knocking the door, but the teacher was there!! Maybe the whole class will think that I'm a really rude student..
And then, when I went home, my friend called me that A asked my phone number. I couldn't believe it! Maybe he just fooling and lying to me again. So, I asked my girl friend that I can trusted.
Actually, he dragged A to my girl friend then he asked her to say my phone number loudly, then he asked A to repeat it. So that doesn't mean that he asked my phone number!
He already said things that made me happy but actually that didn't happen!! But, will he keep remember my phone number? Hope so..

but..

Forget it, he must be forget it right away
