Big Girl Panties

Marty 1:  OMG - I looked in the mirror.
Marty 2:  Well, duh, most of us do that at least once a day to be sure that their hair doesn't look like something a brush hog spit out alongside the road.  And your point is????
Marty 1:  (whining, incredulous voice) There was an OLD woman staring back at me.
Marty 2:  BWAHAHAHA - what have I been freaking telling you?  You are OLD!  Geeze - you are 60.  That's like when dinosaurs roamed the earth.
Marty1:  (small voice) But - I don't wanna be old.
Marty 2:  (mean, sargeant voice) Tough cookie lady.  Get those granny panties out and wear 'em.
Marty 1:  NO.  Don't want to.  I want my big girl panties. 
Marty 2:  Hmmm - maybe we should review ZUMBA on Tuesday night.
Marty 1:  (defiantly) So what about Zumba?  I kept right up with those young chickies.
Marty 2:  Um yeah, I could see that.  Good grief - wiggle, wiggle, rah rah rah, cheese, butt gyrating until I thought yours would get stuck and fly off!  You looked like a demented cat on catnip.  You sweat so much, I thought I'd have to swim out of that room.
Marty 1:   (growling)  Quit picking on me.
Marty 2:  Well somebody's got to talk some sense into that rock you call a head.
Marty 1:  What do you mean (snarling just a tad).
Marty 2:  (very reasonable voice)  How old were those women at Zumba.
Marty 1:  20, 30, 40 (small voice)
Marty 2:  You idiot - what possessed you to try to keep up with a 20 year old's butt wiggles and rah rah rahs and grapevine kicks and twirls and chainsaws and wiggles and ......
Marty 1:  (screaming) SHUT UP!  I put on my big girl panties and I was determined to stay up with them young uns.
Marty 2:  (dripping sarcasm)  And how did that work out for you?
Marty1:  (ignores the question)
Marty 2:  (louder)  Hey old woman - I said - How did that work out for you?
Marty 1:  (very small voice)  I did OK.
Marty 2:  (so much sarcasm, you are drowning in it)   REALLY!  And did I see you walk out of class to visit the porceline throne with 10 minutes left to go.  What was that all about?
Marty 1:  (very cross and snappy)  Well, o.k. so I got a little hot, sue me.  So I had to visit the porceline throne because of that.  Sue me.
Marty 2:  I rest my case, lady.  Take those big girl panties, toss them in the back of your drawer and act your age.
Marty 1:  (almost whimpering)  But I wanna wear my big girl panties.  I want to ride roller coasters, I want to stay up with the big girls.  I want to do all the things I did when I was 20.
Marty 2:  (huge sigh).  Dear Lord, my work is never done.  Rerun on this conversation tomorrow.
