So this girl was at one of those house parties that are a staple of Nigerian social life. She and one of her friends were at a table with a bunch of guys. It was a slight mismatch in that there were two girls and three guys.

As these things do sometimes, the conversations soon paired up leaving one guy the odd guy out. To her mind it was conversation and relatively innocent flirting. However a guy who was at the party disagreed and thought that there were sparks flying all over the place. The guy took it upon himself to put out said sparks, telling the girl that said dude had a girlfriend.

This is clear burning of the cable, based on the guy code established from olden times that guys do not interfere with other guys relationship business. However it doesn't change the fact that a guy can and should violate said guy code when friends or family are involved.

However in this particular case, the guy was himself toasting the girl, and so this doesn't fit into the standard friends and family divide. In fact it's clear that he was only informing her of the guy's couplehood to ensure that he would still have a chance.

The girl's take on it is that she didn't like the guy like that and so any possible gratitude for the information is completely negated by the fact that he did it mainly for his own gain.

I still think that she should cut him some slack, after all as they say there is no such thing as a truly selfless act :D
