How to stop crying

[somedayillbesaturdaynite]

I cry far too easily. When I can feel that lump forming (or even before) I know there is absolutely nothing I can do to prevent the tears. From the way others talk they seem to be able to stop themselves crying if it's not convenient (eg in public). How the hell do people do this?!

I'm the same. Anything sets me off, so watching with interest.

Do you find some days you just know that it's going to come out at some point? I am hoping someone has some techniques that help.
