this is a trick question guys
1. watching Cocomelon meaning that you know that show because your toddler son/daughter watched it, and you had to watch it along with them while taking care of them.
2. Middle aged, what does exactly means by "middle" nowadays anyway. people nowadays fall into a great depression and died inside as a person before they're even turning 50, so middle aged nowadays is more likely about within the choice road of where you would wanted to take your life.
3. being senile means you have no idea what is going on anymore, new trends and meme comes and goes in a speed of light you're having a hard time to keep up with the trends, because if you didn't keep up with them all your classmate will mocking you for being a caveman.
