Student or Learner
please help with the meaning of following sentence:
"And oh, letís not forget the old peek in the mirror. If youíve been known to strike a fashionably cynical pose once in a while, donít be surprised to see the kids trying it out."
Does it mean when I was a child and looking my own body in the mirror?
No. In this case, old means customary.
Also, we would say "look at myself," not "look at my body."
I'm not a teacher. I speak American English. I've tutored writing at the University of Southern Maine and have done a good deal of copy editing and writing, occasionally for publication.
