Another tip for you today!
When you want to say "no" to somebody about some invitation or some question or something you disagree with.
In English, we often don't say "no".
We say lots of different thinks to mean "no".
So if someone asks you "Would you like to go to this place?"
You could say:
"I'm not so keen on that " or you could say
"I don't know"
"I'm not sure" or you could say:
"Maybe another time"
So often in English we find ways to avoid saying "no" because to say "no" sounds a bit like conflict between people and we don't like conflict we all like to be friends, we like to make other people feel that we like them. So, remember in English there are always lots and lots of different ways to say "no".
