why do people resign so easily?

I've played against two people in live standard today who moved too quickly and ended up losing their queens in the first 4 minutes. I know that it's the strongest piece, but that doesn't mean that they have to give up as soon as it happens. One of them was even over rank 700 (I was 540), so he probably has more experience and could have beaten me. I don't get it.

Losing your Queen right away is almost always fatal and it's no fun stretching out a lost game unless you're a masochist. 

What's the point of playing on when you're down a queen? That's a waste of time.

It's not fun to play a queen down. Believe me, I know.

Depending on the layout of the pieces a player may be able to pull a draw off so quiting early is not the best option, and what better way to develope strong chess skills then to fight your way through a loosing game:)

@Dodger111, ChessBrilliany38, Robert0905, did you notice the ratings involved? His opponent was over 700  People rated 500 points higher throw away that kind of advantage sometimes. I know 

When you are both in the 500-700 range, it's entirely possible the other player will blunder their queen in excitement.

Heck, I've even had this happen playing another ~1300 player. I couldn't believe I'd blundered my queen and played a few moves to see what would happen, and suddenly he gave me his queen!
