Lol - they piss you off, don't they? I'm not a morning person at all. Takes me a good couple of hours (and some strong coffee) to properly wake up and fully focus (after 8-9 hours of deep, usually undisturbed sleep).
However, once done, I'm a cheery, even-tempered person, not prone to bad moods (most probably because I'm happy and contented within myself and love my life), and so that's the type of person I like having around me (I detest the opposite: moaning gits who never seem happy), and so fortunately my wife's the same, in terms of temperament
We're both very much 'glass half full', optimistic, cheery people - just not first thing in the morning!
Marco.
