Stop in for a cup of coffee

Well I just had a somewhat heated discussion with wife over tax’s and budget junk as we are on the doorstep of Retirement. At one point she crawls up onto my lap (She is small) and I immediately think of the Friends skit where Phoebe explains to Monica how to manipulate Joey by pressing her body against his. Monica explains that will never work (it did). So I explain to my wife that she simply cannot fix everything with sex as she gets a bit closer and looks me in the eye and asks.....really? Game, set, match. I don’t even remember what we were arguing over.
What is this 'sex' of which you speak?
