Do you think he purposely hanged by the other side of my building?

So there was this guy who would purposely be at places that I will be, he would sit at the bus stop near my building. So I started to take the route on the other side of my building and today I saw him with his friend. The stalking stopped for awhile. For like two weeks. Then today I saw him on the other entrance of my building. Do you think he did it on purpose or is it only chance
