When you think about it, tabletop roleplaying is in some ways a pretty silly activity. At least when done properly.
But hey, it's a way of having fun. Even grown-ups need to play and engage their imaginations. Roleplaying games are just a somewhat more sophisticated means to that end than what children do naturally when they play make-believe.
As a GM, much of the creative aspects of the make-believe fall on your shoulders. Which is why it's so good when a player comes up with something cool and potentially dangerous that you can co-opt outright and work into the game.
