1. I am eating dinner late at night every Monday.
2. I am eating dinner at 8p.m. every night.
3. I am eating dinner now, can I phone you back later?
4. I ate dinner just now in the restaurant. I am heading to a concert.
Please help to check the above, thanks & regards.
In sentences 1 and 2, change the present progressive to the simple present.
Put a space between "8" and "p.m."
Can you see the major error in #3?
4 is fine.
