Welcome to "The Gods Are Bored," practical parenting and problematic parroting. Watch your fingers!
My daughter The Heir is leaving for her first year of college.
I know how colleges work. The students, left to run free for the first time in their lives, stain the upholstery with mad abandon.
All you can hope in these situations is that you've set a good example of proper furniture maintenance and quick clean-up of any unintended spills.
The Heir has her own taste in upholstery. I've encouraged her to have a big, broad, flexible outlook. Let other folks flock to La-Z-Boy. She can take the sofa less traveled. Maybe it once belonged to Aleister Crowley (notorious for spotless ottomans).
If anyone wants to leave a good-bye wish for The Heir, just pop onto the comment sheet. You need not restrict your advice to upholstery care. She already knows enough about that.
