Oh hell. I really hope your father never ever shows up.
First of all, I hope you've got your license and paperwork in order, posting that on here, when really, I thought that was supposed to be medically motivated and not publicly advertised. I'm not entirely sure of the laws here, so I'll leave that to one of the law enforcement types that are on the network and might see this.
Second of all, my wife also grows plants of the nursery variety, so you'd probably enjoy talking at her. I'm certain she'll see this and I'll get dragged there for drinks and snacky cakes or whatnot, and I'll be looking at your pots that have nothing in them yet. And that's probably good for the cancer patients, because if I touch the bloody things, they'll crumple up and turn black. I've got a black thumb.
