I think about the good old days.
What do you like about the good old days?
The good old days were good and yet we take it for granted.
You might be nostalgic for simpler days and miss your childhood for a reason. This could mean that you're exhausted from the current situation in your life, so talk to someone about what's troubling you right now.
I don't want to talk to anyone, I wanna watch sesame street with my daughter and go back to when I was a kid and things were easier.
Things may have been easier back then but you were a kid. Trying to get away from your responsibilities as an adult won't make them any easier. It will only make them harder.
