This is just one potential reason for a person to "brushinwalk" others include: to find something in the house, to play out the last minutes of a videogame, to grab pajamas, ADD and ADHD could all be root causes and outside factors.
Most people who are not brushinwalkers do not like brushinwalkers.
"I slept over at my new girlfriends house the other day I found out she was a brushin-walker, I'm not sure how I feel about that. Its kind of annoying."

"Dude, I totally forgot! Sorry man, it's really not that big of a deal."
