I knew a guy in college who could belch the Star Spangled Banner.

Quite impressive!

It's best to be a lady or a gentleman. Every little thing that you do affects your relationships, even something as ostensibly banal as bowel movements and the digestive process. When you start disrespecting each other on a small scale, it's only a matter of time that you will do so at a much more serious level and start taking each other for granted. Let's keep something sacred in the relationship. This is how you start chipping away at the love, when you disregard each other on a small scale or let yourself go. It's only a matter of time that you start dressing like a slob and not taking care of yourself or your appearance. You are signaling to your mate that you are not interested in pleasing them. Or worse, you don't care if you displease or disgust them. Then, you wonder where the love went and why they are more attracted to someone else and are leaving you. Pay attention to everything you do.

I restrict myself to drinking beer on the few first dates and don't really start hitting the hard stuff until it becomes a relationship.

Actually, I did grow up with brothers. That is no excuse.

I only fart rainbows.

Lol.. so how long after you've been in a new relationship.. do you wait before you let them... hear you burp.?.
Or worst yet.. you break wind..oops. excuse me.. ....
