Could you tell me some usual Airport Pick Up expressions or words? I have to pick up some foreigner friends at the airport. But I have no experience. What should I say when I'm picking someone up or what are the conventional words?

The usage of "would"? How do you use "would"? How can I use it like a native speaker does?

It this a correct sentence? "You have no idea how strong the future you will be" Is it a correct expression?

"strike" and "hit" What is the difference between "strike" and "hit"? I need some examples, thank you
