Onions!

The last thing that i did for work today wa, cutting onions, and onions are a bummer!
Everytime i cut em, they make me shed a river of tars, and it makes me feel kind of emotional, like i'm actually really crying because something bad or sad happened to me.
For a long time i've been trying to figure out and solve the problem of crying when cutting onions, but it just dosen't seem to work.
Maybe my eyes are just really sensitive or something, so anyways, i really want to know what i can do in order to not cry when cutting onions.
