It's a day made by me that every one comes together to eat a potato for world hunger and if you eat a potato you donate a potato

A day where sisters all get together and go shopping, exchange gifts and have a meal together while sharing childhood stories about the times they were kids and take photos of that day

I think for the the birthday count down me personally i think there should be a place where you could put the time you were born so you could have the exact countdown. That would be really nice.

Release dates for Video games (Console, PS2, PS3, PS4, XBox, Nintendo, 3DS, Wii, Xbox One, Xbox 360, PC, Mac, Steam, Vita)

Go to school or work dressed as the craziest thing you can be. Don't let the government tear down our fun!
