That Fish in the Pond

It feels like you have cast out the bait, u wait, and you start to feel the sun can be so hot sometimes, and then things got worst, the sky turned gray, it started to rain, but u are not giving up, u can see that fish u want swimming around, and later another guy came, cast out the bait, And in minutes, he got the fish that was in that pood, you went :0, then u cant help but go over and ask what bait did u use, he answered apple, then u go isn't that a Toman(predatory fish), that guy, yea, but this one's a vegetarian.....Great, and you start to wonder, how did he know that the fish's a vegetarian??
