“You know me: I'm not one to chitchat on the phone for too long.”
You got a telephone call from your nephew. You've been talking for a few minutes, but now you want to end the conversation. You usually don't like long phone conversation. You say this.
You know me: I'm not one to chitchat on the phone for too long.
Say this when you're reminding someone of something about your personality or habits:
You know me: when I say I'm going to do something, I do it, no matter what.
You know me: I'm terrible with numbers.
Another version of this is "You know how I am."
These expressions are only used in spoken English.
This is an expression for talking about things that you don't usually do. It means "I'm not the kind of person who ___." For example, if someone offers you a drink and you like to drink, you can say:
Of course! I'm not one to turn down a drink!
Here are some other versions of this phrase:
I'm not usually one to argue with strangers, but that guy got on my nerves.
He's never been one to back down from a fight.
"Chitchatting" means talking for entertainment. When you "chitchat" with someone, you're not really saying anything important.
The word "chitchat" can seem a little negative in sentences like this:
I don't have time to chitchat!
But it doesn't sound really negative, so you can also say things like:
We had a nice chitchat while we were waiting.
