You wake up on your birthday, and suddenly you’re 20. It feels like just yesterday you were 19, and now you’re in a whole new decade. The classic meme template with the confused Jackie Chan WTF holding his head works best here.
It’s like you blinked and a whole year disappeared. The confused meme face is all of us trying to do the math and figure out where the time went. 19 to 20 just doesn’t seem like it should happen so fast.
There’s no real answer for how fast 19 turns into 20, but at least we can all laugh about it with this meme.
