hi group, I have 2 scenarios here...I'd like to know how we express it in everyday conversation... 1) when we try to say we agree with someone, what can we say besides " I agree" or " I concur" ? any less formal way of saying that? 2) If me and my friends are setting up a time to meet, and they suggest a time when I already have stuff to do, like going out with other friends. what do I say? can I say " I am already scheduled that day." ? Also, what do I say if I want to express that " I already have a dinner appointment that day." not sure if it's correct....but to me, the word "appointment" sounds like a more serious meeting like a doctor appointment or apointment with professors at school.... Thanks a lot!
