Four Ways Your Smartphone Can Ruin a Date

1.) Using it for anything other than an emergency: Only a few things count as an "emergency" during a date: Your boss calling, a close family member getting sick, or somebody nearby needing immediate medical care. If you absolutely HAVE to make a call for some other reason, let your date know upfront, explain why, then briefly excuse yourself.

2.) Keeping your phone on the dinner table: When you're at a restaurant, your phone should be kept in your pocket or in your purse, on silent! Keeping it out on the table, or anywhere in you or your date's line of sight, is just rude.

3.) Texting instead of calling: Text messages and emails are fine for some things, but it's impersonal compared to a phone call. So when you're trying to make plans, or if you're running late, call instead of texting.

4.) Posting pictures and updates to Facebook and Twiitter: Don't post on social media unless you've cleared it with your date first. That means no status updates, no "checking in" or "tagging them, and please do not post a picture of your food.

I will admit I've done some of these but not on first dates. I've done it when I've been with the guy for a while. Some of it is just common sense!
