果物 Fruit! 食べ方 How to eat!

So I know it fs been awhile since I've written but I thought I fd come back with something random and not very major at all: school lunch today.
Well, actually, there was no school lunch today... but people brought their own bento, a box lunch. I bought mine at a local store and complimented it with a peach and some water.
Every day I bring a bottle of water to school but as it is so hot it is never enough so I re-fill it with school water. There is a cooler with ice tea in it but I feel like it never satiates my thirst, even though it tastes good. In America the cooler would probably be ice water... which I miss very much. So, I make do with the school sink water despite everyone's astonishment that I'll actually drink it. (Water in Japan is perfectly safe, at least as safe as America anyway. But people just don't drink it except at restaurants).
With the peach, people were astonished with two things: one that I didn ft peel it first. People peel EVERYTHING here... grapes(yes grapes!!!), persimmons, apples... they never eat the skins. So perhaps to them it looked like I was biting into a nice big orange without peeling it first! Also, they were astonished I would eat any fruit without cutting it up first. Apples and other round fruit are cut and peeled, oranges peeled and quartered... everything is peeled, cut, and prepared extravagantly. They fact that I was just biting into my unpeeled peach got giggles and confused looks. So I asked a friend, gWhy does everyone think it fs so strange? h She said, gBecause it IS strange! h I asked if there was a reason why you have to peel and cut everything and she said there was no reason. PEOPLE JUST DON'T DO IT HERE. (That's an answer I get a lot to why people here do things only a certain way. Like why it's unproper for a woman to sit cross-legged. Cross-legged happens to be my favorite sitting position but everyone here sits on their legs. Ouch!) But I'm sure there must be a reason stemming from somewhere. I can think of a few (though they don ft rate high enough for me to actually care): it fs neater, some people don't like the taste of the peel, you can eat it with chopsticks if it's cut up. But for me a peach or an apple has value in their geasy and delicious snack appeal. h That is, I buy and eat them because they are ready-to-eat, no fuss, delicious snacks that nature prepared for me the way they can be eaten easily. Cut fruit is for parties! It belongs next to the little hot dogs with the tooth picks.
Needless to say, it's funny how just being myself can see so odd here to some people. I wonder what habits I fll bring back that make other Americans confused or amused.
