Social media has completely taken over the world.

If it's not Facebook, it's Instagram. And if it's not Instagram, it's Twitter. The possibilities of social media are endless, but so are the totally pointless traits that modern-day technology holds.

TikTok - the video-making app that allows users to create short videos that very quickly go viral - is one of them.

But one TikTok video with a rather unexpected ending has gone viral this week...

TikTok is absolutely taking over the world.

It's pretty unlikely that you'll see a teenager who isn't obsessed with the social media platform.

The majority of us adults are too, with us posting every inch of our lives on these apps and communicating with others through them solely.

A lot of social media apps provide many purposes...

People can actually earn a living through social media, such as selling things on Instagram or starting a business through Twitter.

But there are some apps that aren't so productive...

And TikTok is one of them!

A lot of people are struggling to understand exactly what TikTok is...

Basically, it is an iOS and Android app made for creating and sharing short lip-sync, comedy, and talent videos.

It went viral pretty quick ...

It was the world's fourth most downloaded app in 2018, beating Instagram and Snapchat - which is a pretty big achievement!

It has been argued that TikTok is better than Vine...

Who remembers Vine? Launched in 2012, Vine was a short-form video hosting service that allowed users to share 6-second-long looping video clips.

TikTok videos look a little something like this...

And it has to be said, the majority of them are rather entertaining.

Animals and TikTok are the best combination.

More and more people jumped on board the TikTok bandwagon and started getting their beloved pets involved.

The rise of superstars...

People began getting more and more creative, including autotuning this kitty's annoyed yowls.

Some are just plain weird...

It's a mystery as to what goes through people's heads when these types of TikTok videos are made...

It can now be established that TikTok is just a space for weird videos.

But some people still cannot get their heads around it!

But there's one new TikTok story that's taking the internet by storm.

It's one of the most heartwarming we've ever seen.

Derlin Newey is 89 years old.

None other than TikTok creator Carlos Valdez.

Fans loved Derlin, but were sad to see him working way into his advanced years.

So Valdez decided to start a fundraiser.

And quickly raised a huge sum of money for the delivery driver.

"'We collectively collected a gift for you, and I'm here to deliver that gift to you on behalf of the TikTok community."

Derlin was visibly touched by the gesture.

"How do I ever say thank you? I don't know what to say," he sobbed.

"He needed this. I'm just glad we could help him. We just need to treat people with kindness and respect  - the way he does. He stole our hearts," explained Valdez.
