Hey now, Mythbusters proved that you can still teach an old dog new tricks. XD

Apollo's lived a hunter-gatherer lifestyle his whole life so he doesn't feel the need to be fancy about things. The main difference in their experiences seems to be that Geddoe's used to traveling and occasionally encountering civilization, or at least other people in non-hostile situations, whereas Apollo's used to having at most one other human around and a base camp to return to every night, so he didn't have experience finding or setting up campsites before he came here.

Apollo was raised by his Grandpa, so my assumption is that it was a result of his Grandpa not thinking to mention it, since they were both guys and no girls were around. I'm still trying to avoid him walking around town naked, but in the case of going swimming I have no choice but to bring it up otherwise I'm being OOC, since he's shown on-screen as taking that approach (granted, Silvia looking up and discovering that she's at eye-level with his junk is a pretty funny scene). One of those awkward situations in RPing I guess. ^_^;
