I danced last night?!

I danced yesterday. It's not a big thing, but to me, it surely is. I like singing but don't feel like dancing, I don't know why. I have never danced for almost eight years. Every time they invited me, I would say sorry, which always worked. But Last night, I should danced and almost a whole night! I thought I was crazy! When a man stretched out his hand(s) to invite me, I felt a little surprised and politely refused, saying I didn't know how to dance. He, of course, didn't believe me, but just pulled me out of the seat to teach me. I felt embarrassed. Before I could say a word, we danced to the music. Oh, dear, what's going on with me? I hate dancing.
