What should I say when I can't understand what someone is saying,
-especially because they are using difficult language.
"Sorry,- I can't follow what you're saying."
I can't follow you."
"Sorry,-I'm having difficulty following you."
"Sorry,-I don't understand what you mean."
"Sorry,- I'm not sure if I know what you're getting at."
"I can't understand what you're trying to tell me."
"Could you rephrase that ?"
"Sorry,-my English isn't so good,-could you try explaining another way?"
