Tomato Tamato

Why are tomatos classified as a fruit and put into the fruit category? I mean it's a vegetable. You put it on burgers with other....vegetables (lettuce, onions, pickles, etc.) When you walk into a grocery store its not hanging out in a bin next to other fruits like the strawberries, apples, bananas, etc. it's over with the other vegetables like cucumbers and things. So I think it should be classified as a vegetable, it's already thought of as one and it hangs out/ is placed with other veggies, so lets make it easy on everyone and this whole debate and call it a tomato. When I think of fruit, I think of sweet things i can cut up into pieces and throw in a bowl all together to eat. And a tomato in my bowl of fruit with kiwi, pineapple, strawberries, grapes, etc. well... that would just be gross. So lets clear this all up, call it a veggie, continue eating it like a veggie, with other veggies, etc. and let it keep its relationship/friendship with the veggies it hangs out with grocery stores.
