I just felt like writing

It's close to the end of the day and I'm utterly exhausted, which frankly isn't atypical anymore. For some reason (which I'm currently blaming on a sinus infection that has been plaguing my body since 3 months now--and yes I'm on round four of antibiotics) I am insanely tired all the time. It's currently 7:28 and I could fall asleep right now. This is what my life has come to...27 and I'm in bed on a majority of the nights by 8:30, 9:30. In fact I attempted to stay up late the other night to see how my body would react...and the next day was full of irritation.
And for whatever reason today it became apparent that people often forget to be grateful for what others do. I try in my own work environment to go and talk to people and always thank them for what they do and let them know I appreciate them. But I do think people are under-appreciated. What happened to people saying a simple thank you? It's two simple words that take all of a few seconds to say and honestly means a ton and can change an attitude around.
I've wished many times people would just say a simple thank you for helping me, or thanks, or some form of gratitude. Having a thankless job is really difficult and quite discouraging at times. I try and say thanks to the custodians as I see them empty the trash or wash the windows, or scrape the gum off the floor, or other random things like that. I doubt they even know who I am, but I figure at least they got recognized for something albeit small.
I guess the brunt of what I'm trying to say is that I'm just glad for people who do their jobs and I wish more people would express it. Now I would really like to go to bed.
