I Have Never Been On A Date

Well it's been soooooo long since I've been on a date so it kinda feels like I've never been on one. I met this guy online recently and he asked me out tomorrow and we agreed to meet somewhere public to interact physically.

So, I'm kinda nervous because I've not been out on a date in soooooo long I'm like..what do I say? How do I react? It's all nerve racking but I'm looking forward to what happens eventually.
