I nearly didn't post this, but as you've had no replies
Only you can make a decision wether to get rid or not...??? I've had old bill knock on my door twice since growing (both mid grow) but felt they couldn't smell anything because of my filtration ( but saying that I've recently given up tobacco after 20 years and can now smell my grinder in the draw!) first time was similar to you and warning me of local car break in's, second time was for an altercation with a neighbour... Both times they didn't have a clue/ had other things on their mind
From your post feel good that your family member answered the door and not you ;-)
If I had to offer any advice? I'd say don't worry, relax. Sit down and think if you could deal with another knock on the door?
Thanks for the reply man. I've got 6 days to go and was shitting bricks. I'm glad it was a family member as I may of been a bit twitchy lol. Hopefully it was a legitimate follow up. Fingers crossed. Thanks for the reassurance man much appreciated
