So they've gotta be over 40-yrs old...

Acting on a tip, I drove over to the west side of Portland on the hunt for a couple agaves...And found them! Walking up to photograph I spotted someone in the driveway, so I asked if it was okay to photograph the agaves. She must have thought I looked fairly harmless and shrugged her shoulders and told me to go ahead. I could tell from her reaction she didn't have a real vested interest in the plants, but I thought I'd push my luck and asked if she planted them, nope they were the work of her dad, planted when she was just a baby.
Now what you need to know about me is I have zero ability to judge someone's age. Back when I worked retail and it was customary, when accepting a check, to ask to see ID, I always played the "how old are they" game in my head. I was always wrong. So she must of sensed the fact I was trying to decide if it was okay to ask her age when she shared, "so they've gotta be over 40-yrs old"...
