If you don't want to feel like your ex-boyfriend (with whom you split amicably) is following you at less than 3 paces every second of your 10 hour day, so close behind that with just one misstep, you'd feel his breath on the back of your neck, then I do not, I repeat, NOT recommend that you use the shaving cream he left behind in the linen closet to shave your pits tomorrow morning.
Very unsettling. Double that advice if your ex-boyfriend is under house arrest.
