Depends. At home, if we're at the table I like to look out the window into the back yard. Depending on whether the oval table is oriented long-ways or short to the back door, I'll either be along side of or across from Himself. I like to look at Himself, but the birds can be more entertaining while chewing.
When out, we sit across from each other no matter if it's a booth or table. Himself really prefers a booth, so I usually let him get his way (it happens so infrequently
). I get really excited when the restaurant has the one-side-booth/one-side-chairs arrangement. My main concern out, thought, is that we're not directly under either a HVAC duct or a speaker.
If we eat with his sis and BIL, it depends on table or booth. At a table, we go around the table girl-girl-guy-guy. That way we don't have to talk across each other, since the guys are always talking computers or financial stuff. *yawn* If we're sharing a booth, it's couples side-by-side with the girls across from each other, as are the guys. Again, the talking thing.
I prefer to seat facing entrance. So depending on the place it may be either or...
Not that I believe in "past lives"
Charlie, but I'm thinking we each must have been a detective or a cop in a previous life. I always want to see who's coming in the door, too. Just in case, you know.
