  ANSWER: You're right, in my book, it is. This concept floats in my head nonstop. The elderly and alot of times Modest youngins/middle-age-ins say it. "Leave some to the imagination" But hello, we should NOT be imagining such, me cher! Now, think it out. We leave things to the imagination. But it's a sin to imagine such!
 Why do we say it, why do we believe it?! Yes, COVER UP but do not go off imagining somebody if they were immodestly dressed!
 You hear stories about "Typical Teenage Guys" and all about how they are unloyal and blah blah blah and how they aren't in it for the long haul just a fling etc! But you know, maybe each guy is actually different. Okay example:
  Take 2 guys, a Very Worldly guy & a Born again Apostolic guy are there going to be opposites are or are they going to be the same? Take 2 girls, are they going to be different?
  Now, this is not only a Guy's subgect. The UPC/UPCI religion makes it a standard for a true Pentecostal boy/guy/man to wear a shirt with sleeves and to atleast wear a shirt at all. Isn't that "leaving things to the imagination"? Yes, it'd be classified as so.
 Should we gals and guys be sitting around imagining what is to be left alone? Why no, last time I thought it over it wasn't!
 We should be praying agaisnt these things Satan's throwing at us! No, I'm not perfect but tell me you are??
 Okay we may devote our lives not to seeing anything but go to Wal-Mart and walk around for a hour. You're garunteed to see atleast three shirts having so low that it's barely a thread and shorts that are half a thread. You'll see baggy pants flashing underwear.
  So contemplate on this!
 Yes, leave things to the imagintation.... but  don't  imagine!!
