They don't like to be alone. They really bond with their owner. When not wearing a bandanna, put it with all your other bandannas in a box or a drawer. Bandannas like to hang out with other bandannas. After you wash them, hang them on a line together.
Bandannas are loyal.
Even if all your friends desert you, your bandannas will stay with you. Neither creditors nor thieves will ever take your bandannas - at two bucks a pop brand new, they only have value to you, and they will be yours for life. If you do lose them, you will always have enough money to buy new bandannas. You can put your bandanna around your head, over your head to make a cap, or around your neck. So you can always have your bandanna, and if you do, you will never in your life be alone.
