Last person texted? According to my phone's log, it was a colleague of mine at work, 11/4/2011 (that's seven months ago, not nine days ago, BTW), but I'm fairly sure I texted my Dad sometime last month... The guy at work has brains although isn't fighting fit[1], but I'd take him over quite a lot of people as a companion at The End OF Days. Dad's not in his prime (either), but I can't see a problem, on the whole.
Last (game) weapon used. First-person-wise, stone pickaxe most recent, but if that doesn't count there's the iron sword. If the pickaxe counts, a bare fist might
actually be the most recent. Last weapon to be
caused to be used, in a third-party sense, was either a crossbow or a spear (can't remember which unit dealt with that pesky herd of zombie elk). Or, if unarmed combat is allowed to take precedence, I had a Sim of mine play Punch You Punch Me with the Social Bunny, yesterday.
So, it looks like I'm with bright but not (all-round) physical companions, and may well have to resort to that knife that was mentioned, unless I want to play it hard-core.
Oh, wait... Perhaps I'm entitled to use a power-fist (or something else actually ranged, if not orbital, from that particular genre), if not limiting to computer games. It
might even be a warhound... Can't remember which weapon I fired last from that, but most of them would normally deal with RL zombie menaces, and if I'm allowed to stomp around as well I'm laughing. Me and whoever it is I've got along for the ride.
[1] So... maybe a useful decoy?
