We did exactly the same thing with toothpaste as well as shampoo and shower gel. He leaves the caps off, so he has his bottles, and I have mine.I thought about this one earlier today. I squeeze the toothpaste from the bottom. My husband squeezes from the middle. For a long time, it irritated me every time I brushed my teeth. I always thought I had to fix it. We finally got past this "irritation" when I decided to use a different kind of toothpaste. Now I have my tube and he has his. So, maybe there is sometimes a way to overcome some of the things that irritate us. Did you solve a similar issued?
