Have you noticed that mileage of your regular mpa goes up and down depending on their love life outside the MP. The more outspoken mpa's tell you when they are miffed with their SO's and "take it out" on you...hehe. When they are in the early stages of a new relationship, their mileage usually goes way down and you wonder what's happening. Just experience from the mpa's that can't stop talking about everything.
