Well....I think this is why there are so many divorces and separations these days. People want it every which way but loose. Everyone has faults, I don't care who they are, and yes, the smallest things can irritate some people beyond reason, but I think many people just get irritable with their partners these days because they're so stressed out themselves. Surely you should tolerate your partner's bad habits as much as they should tolerate yours? On saying that - depends on the gravity of the habit!!!
