I'm definitely more of a day person--the night just isn't for me. I get to see the sun shine during the day, which never fails to lift my mood up. You're also able to do a lot of outdoor activities during the day that you simply can't during nighttime, such as going to the park for a walk, hanging out with friends, or playing with your pets. Well, you can do these things during the night actually, but where we live, it's pretty dangerous to stay outside when it is nighttime. d:
My most favorite part of the day would have to be the afternoons, since that's when I get to go home from college (or my workplace, if I'm working that day) and relax. The mornings are my least favorite, as it can get a little annoying to be forced to wake up until you're completely finished with your sleep. Plus, mornings are usually the time when you feel most lazy, which constantly makes you want to consume caffeine in order to keep yourself energized. Caffeine have a tendency to open you up towards osteoporosis, cancer, and a variety of heart-related diseases. If you take too much of them into your body, you're going to cause some major damage to your health.
