Compliments

Is it just me or do women compliment each other all the time?  I just started paying attention to this and it is happening all around me.  Complimenting shoes, clothes...their overall appearance.  Of course, for every compliment there must be the reciprocal compliment back.  I bet the retro-complimenter is lying a lot of the time.  It's not like she can say, 'Oh, thank you!  You...ehhh...well, actually you sorta look like Shrek's girlfriend in that movie.'  Guys don't do this.  Ever.  Or maybe they do and I just look like crap.
