old

It can be a bit of a trip thinking about how you've changed as a person from your high school years to now. It's probably safe to say that a lot of us went from partying every weekend as teenagers to passing out by 9pm on Saturday nights without the help of alcohol. It's all just a part of the inevitable cycle of life!

These people are tweeting about the cringey ways they've grown (or back-pedaled) since their teen years, under the hashtag "High School Me Vs Adult Me."

A quick warning: if you're a Millennial then scrolling through the following will probably make you feel really old and sad. Believe it or not, kids today (AKA Generation Z) will never understand the struggles of dial-up internet, or fangirling the crap over the Backstreet Boys. If you're not feeling old yet, then don't worry because it's only a matter of time!

These memes are proof that time really does fly when you're having fun - or just living!
