If you know me well, you know I don't like birthday parties. At least, I don't like birthday parties given for me.① I enjoy them when theyre for other people, but when theyre for me, I just don't like them.

I remember one birthday party some friends of mine had for me when I was a student at the university. Of course, I had told my best friend Henry that I didn't want a party and I made him promise he wouldn't do anything. He agreed. I should have known better than to believe him.②

On the day of my birthday, we got home from school at about, oh, I don't know, three or half past three. We went inside and as usual I went into the bathroom and started to close the door when suddenly from behind the shower curtain (浴帘), a kind of strange female(女) voice started singing, "Happy birthday to you, happy birthday to you."

And then from all over the room, people joined in. There were about fifteen people hiding everywhere in the room.

They had got my roommate's key and got in earlier. They had all planned to come out of the hiding place just at the same time while singing. I guess I really upset their plans by going in just to wash my hands.③
