Huh. Parrents can be a tad paranoid at times. Though I CAN sympathise with them (horrors! Can't beleive I'm saying that).
If you don't mind my asking, how old are you, Finch? I only ask because I would offer different advice to a 13 year old than a 16 year old.
'rents can be a pain, but they ARE just trying to protect you. Remember that when you approach them about it. It's like getting a b-day present you hate. It's the thought that counts. You have to smile and be civil when you talk to them even when you would like to, well, I just know how you feel.....
I would take Ozzy up on the contact from an official thing....And maybe involve Phil, too, as he IS the owner of this esteemed forums AND a legitimate, tax-paying business.
Edit: Just had another thought! I hope that they didn't hold the packed plants and not tell you about it! Do they realize that will kill the plants?
