say good morning!!!!!!!

when I was a child under the protection of parents, I said "what will we have this morning,mum?" when I went to Junior high school, I lived with an old couple who are my sister-in-law's parents,they woke up very late every morning,so nobody can I say anything to . when I went to senior high school, we had to get up early to do exercises before breakfast,so we usually said "what's the time now? are we late?" when I entered university,I tent to say "today is very beautiful,I am going to ..." and now,As the graduation is coming,roomates are all busy with the thesis ,they stayed up nearly all night recently ,so every morning I woke up ,I like to say"Hi,everybody,did you have a good sleep last night?" and you?
