Let me drop this here real quick (LOL)
some of us are not always in happy mood, all giddy and ready to jump off a fence (wait is that even right but anyway..). Although I am a morning person meaning I will get up with or without an alarm because I guess I am ready for the day as soon as put my head on the pillow and I also have the energy to actually get dressed...that does not mean that I have a lot of energy saying "hi" to everyone. Also I am not explaining myself I just felt the need to talk about that because I know that I know that I am not the only one who's like this.
Some people have different moods doesn't mean they hate everyone or hate life. Yo! sometimes I just wake up fully angry and I don't talk to nobody... I don't like when I am like that. I just pray to God to get the anger out because people will get offended for no reason, not that I was intentionally mad. Is that even normal to wake up mad and pissed off? Like I don't know.
