So me and this guy in two of my classes rarely ever talk but make eye contact every once in a while. Today while I was on my phone in class (we're allowed to) he was looking at my screen twice while I was on Snapchat and Instagram. He then asked why I dont follow him and I was nervous so I couldn't think of anything to say. I follow two of his friends. I've seen his username in the 'likes' but I'm not sure if i should or not.
