Today, thanks to the fact that I had guests over, I used two
important phrases you can use when dealing with guests. These phrases are used to make the guests
feel welcome, and to make them feel at home.
Both of them give permission for them to treat your house/apartment like
they're home.
Be my guest
Help yourself
examples
If you want something to drink, just help yourself.
Can I have some of that?
Be my guest.
If you need something, be my guest.
Treat this like your home and help yourself to whatever you
want.
