In library: What I think~

I'm in library now. I'm writing my blog alone. Very sad, I think my friend coming early. What's more toooo~ sleepy. I want to sleep here.
Now I remember, my ex-boyfriend called me at midnight yesterday!! I surprised a little. There are sometimes this one. I and he have broken 4 years before. However we are good friendship now.
Last Saturday, he and his friend lay for me. It was just I have finished at part- time-job. I surprised a little then too. We went to drive and Karaoke. I've enjoyed.
So yesterday he have drunk. I and him have new boyfriend and girlfriend each other now. I wondered he quarrel with her girlfriend. It my idea was right. I comforted him.
I think sometimes, We are strange?? Everyone has done with them ex-boy/ex-girlfriend??
