Frankly, for me, it depends on the setting.
In general, I'm not a morning person until I have taken a shower and gotten ready. Otherwise, I'll likely be cross.
I'm a little bitter when people try to talk to me right off hand, but, eh. A few minutes after I wake up, usually, I realize "Blah, I can't be mean, that's tacky", so if I have to talk to my parents, I'll talk to them then. Right now, morning is the only time I really see my mom because she has to work so much [income tax season ;;] so I do talk to other people willingly, I suppose.
But, then again, I usually don't have time because immediately after I awaken I make a beeline for the bathroom. ):
However, if I'm a social setting where I may be sleeping with other people - not like that . . [or at least that's what I'm saying for this 8D] - I immediately awaken and am in a good mood, because I want to show people that I'm ready to take on the day immediately. D:
But, in general, I awaken in a somewhat alert state, because I tend not to sleep well. I awaken every few hours from absurd nightmares usually so, yeah XD; So, I'd say, overall, I'm moderately complacent when I wake up. ^^
And, after I shower, at the very least, I become a morning person and feel energized to take the day on! :D
