I don't want you to take a bite out of something that I'm eating. First, that's disgusting. Second, I'll have to throw it away, and third, it is rude. Same with drinks. If you took a sip out of my drink, I'll throw it away. I know it is a waste of food but it was MY FOOD. I won't give it to you. Why don't you buy your own food? It's mine, so don't touch it. One time I was about to take a bite out of my crazy bread when my best friend almost grabs it and says "I want a bite." Thankfully, she didn't touch it or take a bite out of it. I don't give a crap if it was my best friend, germs are disgusting. I said "no" to her. Lots of people would not do that. I see people take bites of their food, then some other person takes a bite, then they continue eating it. GROSS. Same with drinks, person takes a sip, other person takes a sip. People in grade one used to say, "no, I took a bite out of it." Now, in the higher grades, people say "Can I have a bite? I don't care if you bit it already." Disgusting.
