1) Always check the sports listings before agreeing to anything. When your team is on the tube, hold your ground. When any other team is on, say “Well, honbuns, I was going to watch the big game, but what the heck.” This earns critical bonus points.
2) Tell her that the most important thing is that she likes the new clothes she’s shopping for. Let her pick out a hearty selection, hit the changing room, then plug in your earpiece and check the game. Upon each exit, shrug the shoulders, pout a bit, and tell her alternately “hmm, I kind of like it,” “that one’s…interesting…” or even a gutsy “nope, not so much…” She’ll appreciate your ‘honesty’ on the way to buying whatever she wanted to buy anyway. You can ‘appreciate’ it later the one time she wears it.
