How could you deny being here and doing it!?

I don't. My exact words were "I am not denying doing it." You even quoted them.

The question is why you are doing it and why now, and you seem enthusiastic even though you deny that.

No idea why I am doing it. Possible masochistic tendencies. Why now? Because now is when it is happening maybe and another time would be rather anachronistic?

How on earth do you deduce that I seem enthusiastic about it though? Maybe you already put those Asda Y-Fronts on, flew at super speed up here and peered through my roof using your x-ray vision to see me leaping about with glee? You just made up the enthusiasm bit and once again will not admit your mistake.

Typical really.
