After looking all evening I finally found him on Facebook.
How did you find him?
We passed by each other on the street one day; he then smiled at me that's all.  After that he gave me his Facebook account.
It's wrong to stalk others on social media. You shouldn't do that.
It's okay because I'm not a stalker; I just want to see what they are up to.
Yeah but it seems like the main reason you wanted to find his account was just to check in on what he is doing. That's a pretty unhealthy reason to look for someone online.
