I've been on a couple dates recently, and I wanted to share some things that stood out to me. These little things that helped the gentlemen I was with earn points with me, and I'm sure most girls would agree.
Complimenting my appearance - You don't have to go overboard and say something every ten minutes, but I definitely made some effort to look nice for our outing, and it's nice when you notice.
Flowers - They're pretty. Be reasonable, as a dozen red, long-stemmed roses on a first date is a little much. However, seeing the flowers in a vase at home will remind me of the date long after it's over.
Paying for dinner, even after I asked you out - Absolutely not necessary, but a very nice gesture.
Making the most of it - Sometimes things don't go as planned, but having fun anyway is a huge plus.
Post-date text/call - To let me know you got home safe (especially if you live a considerable distance away) and that you enjoyed our date. It also lets me know you're still thinking about me, at least a little.
None of these things are going to make or break an evening, but they certainly add a nice touch.
