Yes--having the house to myself is a beautiful thing.
I might go to the library.
Or just drive down A1A. Or go to this beautiful park down by the river. There's usually not a lot of people there--it's peaceful and so green. I love to get in one of the swinging iron benches, rock, and look at the water.
I can't find a job so I have many of these free afternoons you speak of. When I'm not procrastinating on writing by fiddling around on the TypoC, I like to...
*Read at the beach. One of the perks of living in Florida.
*Take a walk through neighborhoods that are new to me, or through parks I've never visited before (after finding them via Google maps)
*Go see movies at the cheap $2 matinee theater
*Wander around aimlessly in air conditioned stores just because they're air conditioned, coveting material things that I cannot afford but will never bring me the joy I think they will anyway
*Practicing rollerblading and basketball dribbling at this abandoned parking lot around the corner from me.

Okay, so to actually answer the question, regarding times when I DO feel like getting out of the house... I like to go to coffee shops and read, take my dog to the park or for a walk, go to the pool/hot tub at the gym, or sometimes, if I have errands to run/something I need to buy, that is enough.
Masquerading as a normal person day after day is exhausting.
