After watching HIMYM last night, I realized I've committed the same crime before. Guilty as charged: sharing the same toothbrush with a BF.
To my defense, that was when I was younger and didn't think ahead of packing my overnight bag. I didn't live with the guy so it's either use his toothbrush or go to work with a dirty mouth.
I think using his toothbrush was the lesser of two evils. Come on people, you have to think about what's worst here. What if I bumped into people on the train or on the elevator riding up to my office? People will expect more than a nod for hello and if you ever bump into a talker who won't shut up, you'll know what I mean. Yes, I did cringe a little hearing it said out loud but that's my reasoning for why I did it. Come to think of it, I've also borrowed deodorant and their shavers before. But since those are use externally, I guess it's not that bad but still pretty gross.
So have you and your SO ever shared a toothbrush? Is it okay to share objects used for personal hygiene with your SO or is that a strict no-no?
