"cutting sandwich" news and stories

As we wrap up Sandwich Day here at Slashfood (thanks for all the great pics!), I was wondering: how do you cut a sandwich?

I mean, I know how to do it (it involves a knife), but I mean do you cut it down the middle, so you're left with two rectangles, or do you cut it diagonally, so you're left with two triangles?

I think this has a lot to do with our age and the way we were raised. For example, when we're young, eating peanut butter and jelly sandwiches or tuna fish sandwiches and mom cut them for us, she probably cut it down the middle. I'm not sure why this is, but all moms seem to do it. Maybe they think our kid hands can't hold triangles? Or maybe rectangular food is just an easier concept for our kid minds to grasp?

I think that as we get older, something happens where we start to cut it diagonally. Does it happen at around 15, when we're starting to become independent, or does it happen when we're 21, and we actually are adults and we have to stop cutting sandwiches the "kiddie" way.

Of course, I don't have that problem anymore. Some time in my 30s I stopped cutting my sandwiches altogether. How about you?
