Why is it that when i need a hairtie none can be found, but when i don't need one I can find 20 easily?

I leave hair ties everywhere possible. But I still can't find them sometimes..

That's why I started keeping piles in my room, my bathroom, my car, my coat pockets, and in every purse I own. I can ALWAYS find one somewhere.

Lolz😝I swear, My wife just said that exact same thing to me yesterday before work😂🤔smh. 🌹
