Breakfast
Lunch
Dinner
Freakin' hillbillies.
Gotta agree with this. I always get into arguments with my family over what time we're eating because of this. I've actually missed meals because my grandmother asked me to come over for dinner, and I showed up at 5 instead of noon.
My rule: how would you ask someone for a date?
If you ask someone for breakfast, it's in the morning.
If you ask someone for lunch, it's at noon.
If you ask someone for dinner, it's in the evening.
If you ask someone for supper (which I wouldn't do, but whatever), it's in the evening.
