I did something earlier I almost never do ... answered my doorbell when I saw an obvious salesperson, etc. (without a pistol in hand

... but I digress). She asked if I was "K", and said she knew I wasn't "old enough" but was it was concerning the thread title. I'm still quite a few years away (5ish).
What was she selling? There was another guy in the passenger seat of the car blocking my driveway.... so they drove just to see me. I feel so special .... what's the scam... selling ins.?
My dawg was going nutz so I shut it down quickly and shut the door.... sorry, not interested

.
It just seemed a bit strange....
Thoughts?
