This is how I discovered my mom is a stoner.

That smelly smell that smells... smelly.

I strongly believe scent is the sense closest linked to memory

🎶Ooooooh that smell. Can't you smell that smell. That smell that surrounds you. 🎶

My dad always cleaned his waterproofing tools with acetone. So that reminds me of him when I smell it. But then I think about how bad it probably was to always have his truck reeking of acetone and wonder if that contributed to his premature death.
