Good morning!?

Hola!! I just think that why we say 'Good Morning' in every morning. In other day's morning, it was raining, cloudy, or not sunny... It not 'Good' morning, don't you think so?
Any way, I had a part-time job this morning like 6a.m. to 9a.m (4/17). I slept at 6p.m. last night and got up at 1.a.m., so I did my home work and I was just waking and do nothing. If I slept that time maybe I couldn't wake up at 5 and couldn't go part-time job.
I really like my job. Because of my friends, manager, and regular customers. Evrymorning same people come to my convenience store, which is 7-11, and buy same article like cigarette, rice ball, or coffee. I talk to them every times. I remember their faces and they remember me. Some people say, 'this store is kind of weird because other store's staff don't talk to me', and I say, 'I just want to be a friend with you,' 'yea me too, and that why I come to this store and like it.' My store's manager likes to be a friend with them too, so we try to talk to them. I really enjoy to work at there. Please visit me sometimes!! (224words)
