If your date suggests something that doesn't sit right with you, don't do it.While they may think it's a great idea to do shots or skip out on the bill (yes, that was once suggested to me on a date), don't succumb to anything that makes you feel uncomfortable.While it's always a good idea to keep some things to yourself on a first date — especially in regards to your romantic past, but we'll get to that in a minute — when it comes to things that could possibly create problems while you're dating, you want to put that out there.Encourage them to do the same, and you'll save each other a lot of time.When it comes to first date etiquette, it's usually all about trying to take your awesome self up a notch.Not because you have anything to prove, but because first dates are about putting your best self out there.You want to pay attention to whether you're asking questions about them, and noticing if they reciprocate.
If your date shows up in an outfit you detest or has some sort of physical thing that you don't find completely attractive, don't immediately throw in the towel.
Addressing the elephant in the room is always a good idea. If you met through online dating, then take the opportunity to talk about why you're both online and what you hope to gain from it.
If you met in person or because you were set up, again, then get straight to the point of what you ideally want to get out of all this dating.
You need to be on your toes and up for anything, but you also need to keep your faculties in check, because this person — even if you’ve chatted with them for weeks through an online dating service — is still ultimately a stranger.
It's a delicate balance of being open, and keeping your wits about you.
