grinding is the tits, but if you're out and you forgot your grinder it can be a real hassle. we were at a gig a couple of months ago, and we ran out of weed, but luckily a mate of a mate who deals a bit was there, so we got some from him, went outside and realised we didn't have a grinder, we asked soome guys standin outside if they had one, sure enough they did! lol, it was a reggae gig tho....
