Oh okay
If the person interests you.
It's better you follow the person to easily see the post as you said.

The person mustn't follow you back.

Ya, but some will if they like what you post too

Okay
So asking for a follow for follow isn't necessary.

I just post on my waves ya. At least you saw and noticed I posted.

Having my fun and interacting that's more important ya?
