Teasing, or pleasing

Hmm... when you call someone coward, sissy. or just teasing him... are you in fact the one who lose out?

Let's say..
It happens to be drizzling.. one guy (person A) uses his umbrella.. his friends tease him.. saying he is sissy/coward and alike..

But.. in the end, A would not get wet, and will not stink,smell from all the rain and muck, unlike the rest. In the end.. the rest got sick. A doesnt.

So let's think about it.. is the "sissy" person actually a smarter person, since he does things that are intellectually better. And for the rest of the people who wants to be gungho and stand in the rain... are they actually the losers, since they will in fact get the taste of their own medicine (etc. getting sick)? hmm

Let's have another scenario

A staircase.. and a group of friends dare each other to jump down a flight of 8,9 steps? One guy (B) decides to just walk down, and suffers the tagname of "coward" from his friends. the rest jump, and one broke a leg..
so.. is B smarter, or cowardly? Are the rest just stupid and plain show off?
B took a "safer" route, and ends up in one piece. The rest, possibly due to experience, or "know" how to "do it", and therefore able to jump without much injuries. But they already place danger to themselves.. so hmm..

think about it..
do "Cowards", "Sissies" are really what they are called as? Or are they smarter?
