Mature, Adult, Mature Adult? Probably Just Getting Old?

When you think you are an adult, no, you are not.

But if you think that you are getting older day by day, well, maybe you are physically an adult.

Maturity is just another matter, it means you are getting futuristic mentally.

I guess. Yeah, at least that works on me.
