There are several reasons not to park too close to your destination but one is that you may be parking in another residents usual parking spot. If this is happening a lot, and it's always random guys with their antenna twitching, visiting the same apartment, and leaving shortly after, residents quickly put together a picture that what is going on is either sex or drug related.
In fact one lady that works regularly from her own apartment, tells me that her neighbours know what she does and are not particularly bothered as long as she makes sure clients don't park in the spaces near the back door.
My wife caught me wearing ladies underwear and threatened to leave me.
So I packed up all her clothes
And left.
