Hey let's watch the "older" cracks!
As far as advice, keep your eyes open. You make it sound as if you got done mowing the lawn and got on the computer one afternoon and set up a date with some chick you came across on the internet. Many couples search for months or even years before they get a date with single fem. Unless you are a filthy rich rock star that is Brad Pitt's identicle twin your first order of business may be to confirm that this is an actual BIOLOGICAL single fem and that there won't be a hefty pricetag attached to the end of this date that will be enforced by someone named Quido.
