What do you mean by "asset"? Like hook me up with their friends? Cook me food and wash my clothes?
Please explain.
LOL, is it so hard to figure out? Having a sister is like a testing round for interaction with every other female in your life. You get to see what works and what doesn't, all those intimate little details that are hidden from strangers. What makes her happy, what makes her sad, what giver her confidence, what saps it away from her. She will even give you feedback on the women in your life and half the time she will come up with an angle that escaped you. Isn't it marvellous?
And yes, hooking up with her friends is not to be underestimated. My sister's friends were not the type of girls I would normally go for, but they were there when I needed a distraction, and I fucked up plenty of times in my life that distractions were sorely needed and they were mostly there when I wanted them.
A guy I was close friends with had not one or two, but three of them. He's only a three or four years older than me and he's been with twice the women I have. On the other hand, he can barely form close relationships with other males, in fact he pissed me off so bad a couple of years ago I had to tell him to fuck off- and this was a guy I could easily call my best friend. I'll leave it to you to ponder what it all means, "Psychopath".
There goes typing a novel for tonight
