Informal conversation can be used when we talk to people we have known well, or with friends on the same age.

Example : Lending something.
"Hey mate, I need your help!"
"What's the problem?"
"I forgot to bring my ruler. Please, can I borrow one?"
"If that's the case, sure!"
"Wow, thankies!"
"Don't mention it."
