<human>: So here it goes. I'm a 26 male that has completely been out of the dating game for the last 6 or so years. 3 of which I was in a relationship (funny enough, it started on facebook, when it was when first came out). Beyond that for the last 3 years I've done nothing with the other sex.

I went on a float trip 2 or 3 weeks ago and there were a ton of 21 somethings there, obviously new to drinking and what have you. I tried to strike up conversation with a girl there that I found attractive and it was just small talk, which didn't go anywhere.

This float trip was with a group of close friends and then me and another friend went along. I had a good time and participated in group activities and was not an outcast. People knew my name and drinking games helped :p.

Long story short I gathered up the courage to send a message to this girl on facebook after the trip. No response for 2 weeks and 4 days and then today I got this:

Sorry! Wasn't a great week at that time. How are you holding up? Happy late forth of July!

The last girl I had a long term relationship with I also met on facebook but after the last 6 years I think the game has changed. Back then all I had to do was act dumbfounded that we were already friends and keep the dialog going for it go somewhere. All the while I already knew we were friends on facebook because of me drunk adding pretty girls.

I want to try a little bit with this girl because she seems "hip" in the video games and nerd way which is cool and she looks to be a 6 or 7ish on my radar.

How can I keep the dialog going and expect a return dialog with not knowing much about the girl? Acting dumbfounded at 26 about facebook i don't think will work as its been around too long now. It was out for maybe a year back then.

Thanks in advance.

Can you give me the gist of the text in a nutshell?
<bot>: Met a girl on a float trip and got a facebook message 2 weeks later. How do I respond to start dialog?
