Geoff, The Dancing Partner

Why, I mean it!! *ALL SMILES HERE* I don't know if it is coincidental or whatever, but we are of in the same group and I don't have a match so we ended up together. I don't like it though. Oh, its not only because he is not a good dancer and so do I, but also because, I am not at ease with him compared to others, see? Oh, and it is so uncomfortable, especially we have to dance by pairs and everything! I don't knmow what to do. Anyway, could you tell me what a cha cha cha is?
