Yes and No are the obvious answers. Definite, precise and certain. However sometimes in some questions, it suddenly seems ridiculous that the No part should be to do with the doubts that Yes manages to instill in me. So, I errr... However too, sometimes too, in some questions too, I lost my words. I don't know what to say. I suppose it is a quick one to choose between Yes and No. It doesn't take long to say Yes or No. But I've got a feeling it's going to take more than five minutes for me to get round and take turn to ask questions as well. So, what else can I do besides errr...?
