Advantage of being schizophrenic is you can usually get the group therapy rate.
A good sense of humor, (usually means he's crazy)
lack of ego, (good luck)
ability to see things from a different perspective, (he's a man, it won't happen)
willingness to lead or be led, (you're looking for a dance partner?)
and the freedom to speak your mind without feeling stupid or wimpy. (a smart man knows how to appear that he's listening
and taking turns bringing cookies. (you don't want my cookies, perhaps spaghetti?)
As for the type of hikers out there, I once said to a girlfriend about a apparent nut, "It takes all kinds." She replied, "No it doesn't, it's just that we got them". Several good movies touch this subject, so the issue is not new. Yes, there's a good hiking buddy out there but there no guarantee you'll meet them or more importantly when.
As a comedian once said, "I knew she was the one for me when I realized she also had issues",
Suggested movies to watch:
Silver Lining, Playbook - we'll all crazy and sometimes the one is there
500 Days of Summer - basically life is random
Bottom line, hiking is an activity, you'll find all kinds of people, some stranger than others. Not all hikers like all other hikers, some don't even like themselves. Either way, get out there and set what happens, worst thing that could happen is you'll die, but I have it on good authority that that's in everyone's cards, so don't worry about it. Besides I'm willing to wager that if you don't get out there you die sooner
