GUYS, why would a guy see me and then pretend not to see me?

Whenever we were walking along this corridor in work place, he would pretend to be fiddling with his phone or stuffs and basically pretend not to see me.

I want to know the reason why guys do this sort of thing. Why couldn't he just say hi or something?
