One reason why wearing underpants might be a good idea:
You discover your old, scruffy, soft, baggy around-the-house pants have split in the back from waist band to crotch only after you’ve leisurely strolled your dogs around your Rated-G neighborhood with the day-care center on the far corner.
The upside of going pantiless:
your beloved husband points out big white granny panties might have been a lot more obtusive than your demurely flesh-tinted nether cheeks.
If you show your ass, it's good to be lucky in love.
