Ladies, if you were having an affair with your neighbor's husband, wouldn't you want to be as inconspicuous as possible?

I just can't figure this... its really none of my business but I have a neighbor who lives right next door. On the streets, she is known as Sunshine. I have another neighbor who lives 2 houses down, next to her. That neighbor is a married couple. The man who lives there also has a house across the street in which his mother lived before she died. The house is vacant but he owns it.

At that vacant house, I often see the man's car and Sunshine's car parked together. Sunshine has a reputation so I'm sure they're not just having a cup of coffee.

What irks me is if she's going to sleep with the woman's husband, why does she park her car there at that house instead of parking it at her own house and just walk across the street? Sometimes, the lady is even home and I see both of their cars parked there. What kind of ho does this?
