Do not be gross
Be careful not to do things such as belching or picking your nose when you are in front of your date. A). that’s just gross and B)…that’s just gross (redundancy is intentional). The point is, this is not a time to demonstrate how comfortable you are with your own body, it’s a time to focus on the other person (and hopefully not gross them away from your life).
Do not go on a date when you are drunk
This advice should be obvious, nevertheless some people have gone on dates after a booze session without knowing how risky that may be. You want to have a sharp mind on your first date and it only takes one drink for that edge to disappear. Charm your date with your witty humor and not your witless lack of alcohol control.
Do not smoke
Especially when you plan to end your date with a kiss. People normally don’t enjoy kissing an ash tray, so if you do not want to make your mouth smell or taste like one, refrain from lighting up.
Do not eat garlic
Garlic is probably the worst when it comes to making your mouth stink but the principle is the same with anything you put in your mouth; you want your mouth to smell good. Remember, you’re going to be doing a lot of talking and listening (unless it’s a bad date…in which case a stinky mouth may come in handy).
Do not order messy foods
It’s your first date. You will probably be nervous, which means you are more likely to make clumsy mistakes. Avoid the opportunity of wearing your clumsy mistake by ordering food that’s not messy. For example, spaghetti is probably too messy (any sauce flinging pastas tend to be).
