I am sorry to ask this, and I hope you'll see it as the curiosity it is.
Is instagram that necessary? I mean, not in the "Dont you have alternatives?" way, but rather in the "Do you need something LIKE instagram?"/"Do you really need to know so much about your friends?" sort of way. I don't have instagram, and when friends want to hang out or do something or talk, they just call me on my phone. That's pretty much the only way I know about the stuff thats happening.
Anything else I just don't really have the interest to know or find out. I can't see the utility in keeping in such enmeshed, deep contact with people via Instagram. The people I really talk to everyday are on whatsapp and that's usually where we talk.
For some time now I've been wondering if something was wrong with me socially, and your comment put that thought back in my head.
