If you are asking out very emotionally immature women, or 18-year-old girls who are still in high school, then maybe they would act like that. But well-adjusted, adult women (or men) do not laugh at anyone who asks them out. I am frequently asked out by men and I don't particularly like it, but I would never laugh at them. I also don't believe in "levels" the way you phrase it. That is an immature concept. My friends and I simply say "no thanks" and move on. We don't really give it a second thought. We are in our late 20s/early 30s now, but we behaved the same way when we were in our early/mid 20s also. I prefer to date 5-10 years older and certainly don't reject people because they are "too old" until you are talking 20 years older than me. I am interested in career, drive, emotional depth, maturity, and how well someone treats me. Same thing when I was early 20s.
