I've come to understand that words are something that people can use to hide behind, emojis as well.. More or less.
We all know this has happened more than once to us when talking to friends;
You: You ok?
Friend: yea I'm fine
You: K

We know there's something bugging them yet we tend to shy away. Whenever we hear phrases like: I'm fine, it's alright, it's cool, I'm good
We know, or should know that, that means there's something that our friend just isn't saying. And sometimes we don't want to pry because it is difficult to tell when to just leave them be because it's no big deal, or because we don't want to come off as annoying or nosy.

Texting is a brilliant way to miscommunicate how you feel, and misinterpret what other people mean. Don't get me wrong, I love texting to talk to my friends and most of the time it's easier than calling. But on more than one occasion you know when the person sends an emoji such as: 😂😅 or 😆 they, in reality are probably showing no emotion what so ever, or don't really know how they feel.

You have to think really hard and try and (based on the situation) decide whether or not to press on the matter. If you were with the person that day, try and think back to a situation that could make them feel as if they need to hide themselves from how they're really feeling, they might not even know. But be careful because you don't want to offend someone either.

Then again you have to consider that you and you're friend may just be in a happy and joyful mood; in short, even the simplest of words are very complex
