My mom let it slide that my dad used to have "a couple plants."

"What does a marijuana flower look like? I've never seen a plant in flower"

"Well they are... wait, when did you see one NOT in flower?"

"Oh erm... well... Dad used to have a couple..."

Whoa. My dad wasn't in the room at the time so now i gotta figure out how to get the dirt tactfully. It's a family affair!
