If you are ever in a situation where tension has developed between you and a person you were or are extremely close with, due to some conflict real or imaginary that leads to an argument, it is, in my experience, always wise to have a graceful exit strategy that allows for both parties involved to go their separate ways without either party feeling ill will.
In my fantasy experience that is. In my real-life experience it's always been a massive clusterf*ck of irrational behaviors and flying-off-the-handle assumptions that escalates in seconds from a petty spat to a thermo-nuclear level heated exchange that leaves nothing but remorse and recrimination in its' wake.
So yeah, the first one, pay attention to that one. Learn it, live it.
