“If someone wants to smoke in the privacy of their own home, hey, knock yourself out. But other people shouldn't have to breathe that in while they're trying to enjoy a meal.”
You are not a smoker. You go to a restaurant that allows smoking, and the smell is very unpleasant. You complain to your friend that smoking shouldn't be allowed in restaurants.
You and your sister are ordering food from a restaurant to take home. You called your father and asked what he wanted. Now you tell your sister what he said.
Your friend wants to rent a house at the beach for a group of friends to stay at. He asks if you'd like to come. You say yes.
You're leaving next week to study abroad. A friend asks if you're excited about it. You're very, very excited so you answer enthusiastically.
