Oh, I hate being mean and sadly, have not had THAT many opportunities to turn people down(oops, not how that sounds-I mean not to many people have asked me out, not that I am sad I can't say no to more people
) but I always like that I am to busy at this time for anything more but when things slow down, lets see what happens. That way, if its just someone you aren't sure of, you can have a few weeks or months to scope them out and if its someone you REALLY don't like, you can just play busy till they move on.
