What are the signs that a guy is showing off in front of you?

Maybe. Not necessarily. Guys are genetically programmed to compete with each other. Often the showing off in front of you (girls) is not about you; it is about the other guys. Look for other signs that someone actually cares about you. Does he open the door for you? Offer you a tissue if your shoes are wet? Ask your advice about a difficult assignment? Or even just give you a friendly smile and say hello to you? A real relationship has got to be more than something to do with being able to do a 360 on a skateboard or the special ability to fling a pencil into the ceiling tiles. Anyhow, that's what this guy thinks.
