Grief Turns You Into A Leper

What is it about someone's grief that makes other people uncomfortable?

It's like you're not allowed to be sad or something because some people don't know how to deal with it; it's like wrong to make them uncomfortable by being depressed and unhappy about something; and so, you wind up being treated like some leper. Or at least that's how it feels.

After awhile, you just feel like it's better for everyone involved if we just pretend that nothing's wrong, nothing happened.
