Here are my answers for the two questions:
#1) A house
...Well, it just looks like one of those stereotypical houses the kindergartners draw, doesn't it?
#2) Turn back.
We don't know how long either path is going to take. The paths may be longer then the distance I took to get here, and my starting location will likely have water. Or I could be simply too lazy to continue or I hate where I'm going, though why would I be going there if I hate it, I do not know. So, it's probably logical to turn back.
Anyways...there were some interesting answers, so I'll go over all of them.

Interesting observation. I never thought of it that way. Yes, poisonous vegetation...
A very fat candle, indeed. :V
This was the answer I was typically looking for, with the typical reasoning as well.
