Well, first chance I've had to watch the season finale. I think the Rick and Morgan reunion will be interesting, given Morgan was talking about how life is precious now, then saw Rick plug a guy five seconds after he laid eyes on him.
As for the "on the left" thing, the correct way to do it should be, "within arm's reach". On my left however, at this moment, the most likely weapon is a letter opener, which I guess gives me the seconds I'd need to get to the good stuff. Though since I just want to get the zombie out of my way to get to real zombie stopping stuff, maybe it would be better and safer to just throw the printer, also to my left, at it.
