What will you do?

I was going to the library and as i was going, a man spit on me . I was shocked but then maybe he did it accidentally. So, i just forget about it. But.... The next day, i was buying some snack and then as i was picking what kind of food i wanna buy, the same man who spit on me came and spit on me again. Isnt that crazy???? He did it again its the second time already, ewwwwwwwwwww, its disgusting. Fuck me
