Do not dominate conversation at the dinner table with your list of achievements. Most importantly, save the burping contests for the homies. Assuming this is also a movie date, don't try anything funny. No yawning and stretching your arm around your date without her consent. Oh, and save the sweet talk for after the movie.
Nobody likes a bugaboo while they're wrapped up in the plot.
Always offer to pick up the entire tab. Let her know you enjoyed her company and thank her for spending her valuable time with you. And finally, never assume you deserve a kiss goodnight. Well, there you have it. A few pointers for those lost souls who seem to have been striking out the last few times at bat.
