Hi there,

Again another question, help me with your kind answers:

friend in different ways

What's the difference between 'pal', 'friend' and 'buddy'?

Which one do you prefer to use for calling your close friend?what about a stranger (e.g. for asking for help)?

an equivalent expression in English

Is there any especial expression for the situation in which (you want to make someone thank you for something good you've done, though not purposely or even for someone else)?

In Persian we say (mennat gozashtan) منت گذاشتن

I just need to know if there's any English equivalent? 

z sound in español

When does freedom of expression end and defamation begin?

When aren't you allowed to say anything and respect others?

How can you feel this border??

All answer please
