When we have a clear context, can we omit words, phrases, clauses, or even sentences? Because I think they are sometimes too long or kind of wordy.
Is there a rule of thumb or something in terms of this?
Examples I came up with:
I came up with these scenarios; I don't know if they are acceptable or not to you guys.
The contents in the parentheses are things I think we can omit.
A: You played for the varsity basketball team. You must be skilled (at basketball).
B: Yeah, I am proficient (in playing basketball).
A: Do you know Estée Lauder? Their products are good.
B: Yeah, I have an eyeliner (of Estée Lauder) and a lip gloss (of Estée Lauder).
A: I am going to that breakfast shop.
B: Ok, you go first and I will catch up. I will probably have a burger and tea (from that shop).
A: The venue has lots of equipment. We have to know all the devices' locations
B: Yes, we should be familiar (with their locations).
