Please read below text. Could you say why it's necessary to use "I'm making" & "My friends say" in this context, but not "I make" & "My friends are saying"?
I’m taking the opportunity to improve my English. I make good progress, I think. My friends are saying my pronunciation is much better than I arrived...
I thought that it's necessary to use "I make", because it's a fact or my opinion. --> Present Simple.
I thought that it's necessary to use "My friends are saying", because it's an action around now. --> Present Continuous.
Where are mistakes in my thinking?
