You're very groovy and all that, but it's my bike. I don't mess around with the possessions of others without permission, it's just the way I am and it's how I was brought up. All she had to do was ask, she rides with one MC Club, she knows what's what, and she has her own scoot. There's no way I would be so rude as to just jump on her bike. What if I dropped it? She's put a LOT of her own blood, sweat and tears into that thing. What's mine is not hers, and vice versa.
Easy-going is what works for you, letting it out is what works for me. I let people know EXACTLY where I stand, there's no big mystery to it. Cross that line, and you
will experience two things; Me all up in your shit; and Me, no longer in your life. Nothing to sweat about, just the way it is.
It kinda reminds me of when I was pregnant, and perfect strangers would just walk up and start touching my belly. That's just fucking CREEPY, man! Don't walk up and just start touching me, you're invading my bubble of personal space when you do that.
No, seriously. It's a cultural thing, I know, but it's the way I am. (Little kids I can tolerate doing that, others... uh uh.)
