Dating site observation

Match.com: they advertise 75% off of cruises YES! So, I just met someone on a dating site. Shall we have dinner? Naa, too conventional. Movie? Naa, you can't really talk and get to know each other. I KNOW! Let's go on a cruise and be stuck together on a boat for, oh I don't know a WEEK?, where we can learn all about each other's foibles, problems with exes, restraining orders, etc. PERFECT Where do I sign up. Oh, wait! I already did.....NOT!

So, how many dates does it take until you are ready to go on a discount cruise with someone? Alex told me that by the third date, you can have sex (But, I think it is still pretty soon) So, by that standard, you take vacations together by date....ummm....6? Engagement by 10? Grandchildren by 45?

I am so NOT a 'rules' girl! (You know there is a book called "The Rules" right?)
