Is it rude not to follow someone back on Instagram?

[713]

Random people will follow me on Instagram and like my pictures but if I don't know you or you're not a celebrity I'm interested in then I don't want to follow you back honestly..

I feel really mean and really bad though when I don't follow back...so usually I'll go and like a bunch of their pictures...

I just don't like scrolling through my news feed and seeing a bunch of pictures of or from random people idk. It feels weird. I prefer seeing my friends and people I know on my news feed.

I'm even following someone I know in real life and they don't even following be back...I honestly feel like it's rude but I still follow her because I just like what she posts...even though I hate feeling like someone's "fan"...I feel like I can benefit from her, she posts some pretty cool things and gives me great ideas...plus she's extremely pretty...but anyways...
Sorry for the typos...autocorrect -.-

Your train of thoughts makes sense, not rude at all.

well, change your settings to private, that way only your friends can like your pictures.....

Hun don't worry,if you just don't like that person and you are not interested in that person you don't have why to follow back! It's you the one who decides!

Oh and about those friends that don't follow you back all i want to say is
"DO NOT WORRY ABOUT THEM AT ALL"
I mean you aren't going to die just because they aren't going to follow you,and you don't need their ''follow'' at all =)
