After all, poker is just another Liar's game of "Go Fish".
The goal is to be the biggest fish in the pond, no matter how many fish are in the pond and AA is usually the biggest fish in any pond. You could look at the Flop, Turn, and River as food to make you an even bigger fish.
The size of the bet could be considered the bait and it takes a big fish to eat lots of bait. Lots of bait tends to attract some fish and they may just be able to grow into a big enough fish to take all the bait. The action on the Flop, Turn and River will help determine when you should just cut your bait and run.
The first one in the pond usually thinks they can be a big fish, but the more fish there are in the pond, the bigger you have to be. You really don't want to be a small fish, like most drawing hands tend to be, in a big pond, like one with many players. You can also relate the size of the splash in relation to the size of the fish and some players really like to splash their chips into the pond. But is it a big fish splashing or a belly flop, both make big splashes?
The size of the pond is important too. Position helps you determine how big you need to be or if you have the potential to grow into a larger fish. I've seen a few dead whales on the beach, so AA isn't a sure thing, especially in a pond with lots of action. If there is only one other fish in the pond, jump in, the water tends to distort the size of the fish anyway.
