Recently, I got instagram. I really like it and started getting followers... One of the people I started following was my crush, Collin. He has a public account... so I didn't have to request to follow him. The only problem is, it's been like 3 days and he hasn't followed me back. I think he likes me too, and we have so many great memories... and you would think when someone follows you you would follow them back right? I just don't know why... any answers?
