Toothbrush

You know you're not single anymore...when your wife texts you while you are at the store "pick up two toothbrushes: one for you and one for me to use to clean with" and you're wondering what just happened at home....You know you just got a new toothbrush six weeks ago so you know you don't need another new one that quickly...in fact you are used to your toothbrush lasting six months or sometimes even longer...It turns out your wife wants you to have a backup toothbrush when the other gets old...You have a strange feeling you will be using the backup toothbrush a lot quicker than six months from now!
