To "relate to" someone means to feel comfortable with them, and to understand each other. People usually "relate to" each other by sharing information about themselves.

This expression is useful for describing who a sentence is about. It's easiest to understand it with a few examples:

As my friend, tell me the truth: do you think I'm making a huge mistake?

A "wide range" means a lot of things that are different from each other.

This is a very straightforward way to give someone advice. You use this phrase when you definitely know more about something than the people who are listening:
A: I've never eaten that before. Do you eat it raw?

You can also use "You have to ___" when you're excited about something and you want to share it:
You have to try this! It's delicious!
If you use "You have to ___" to share an opinion, you might come across as rude. For example, don't use this phrase when giving friends advice about their relationships, job, etc.
