It can be a date with a hot guy or a flirting session with the guy you had been eyeing for long, if your girlfriend needs you, you got to be there for her. Even if you are getting lucky and she calls you to tell you that she is getting fired (or dumped), you got to put her first. Guys come and go, friends stay for life.
