How do you follow people
The same way you followed the 25 people.
It's as easy as clicking on their username or profile picture and then clicking 'Follow' from the top of their profile page :)
You're following 25 people .....I think you got it.
If you can't follow someone it might be because that person has blocked you. I figured you know how to follow people in its usual way
just walk behind them
You sneak up behind them. And walk casually. Then keep walking and if they ask you, say "my house is this way". Just don't get caught.
You mean to be a stalker ?
the same way you followed the other 26 people :o)
Just click on their username and click the follow button.
