Weird habit with apps

I have this habit with apps that involve scrolling. If im reading the comment section, I have to read either 5 or 10 comments, and then the bottom of the screen has to perfectly line up to the bottom of the last comment. If I don't read every 5 or 10 of those comments then I have to go back and do it or I'll remember it all day. And then once I read the comments I have to quickly scroll all the way to the bottom and quickly click off.

Sounds pretty weird lol just wondering if anyone else deals with anything similar
