I've never had good experience with set up dates. My friends thought they knew what I wanted or needed, and it turned out to be the opposite of what I actually did. All of the guys I was set up with, or pushed onto in high school and junior college are WAY different than my husband. Thank goodness.
I agree it does depend on who sets you up. My sister met her husband through a blind date, but her friends obviously knew what she was looking for.
Oh and to comment on the single/alone thing. I believe there is a difference. You can be single without feeling alone, and you can feel alone without being single. They are two completely different things, and it all depends on state of mind. I have an uncle who is a bachelor, not because he didn't have options, but simply because he wants to be. He said he don't need a woman telling him what to do
smart man! Lol. He isn't "alone" he just doesn't want to get married. He rather enjoys his "freedom."
