Gravity is annoying. "Here, let me pull whatever you have in your hand out of your hand and place it on the floor for you so you have to pick it up again, and I will be doing this your whole life so get used to it". "Here are some stairs, now don't worry I won't f with you this time, I mean look you just walk down one step then the next then CRASH BOOM OWWW BITCH THUD". "Look at that beautiful smile on your daughter's face with the ice cream cone you just bought her, isn't this this just a touching moment except..wait...she's tipping it 5 degrees too far and PLOP, wahhhhhh!"
Gravity, the weakest of the forces in the universe so it makes up for it's weakness by being an ass.
