One thing that is different between b. and I is her love of/my ambivalence towards sweatpants (I don't wear them often). However, I'm a huge fan of running leggings. We're talking back and forth about sweatpants after I had commented that my dress-slacks were baggy like sweatpants when an epiphany hit me.
Me, "Hey Brooke!!" (insert a hee-hee-hee)
B., (long suffering sigh and a reluctant) "what?"
Me, "LEGGINGS can be called SKINNY SWEATPANTS! Isn't that AWESOME!?" (hah hah hah)
B., "No, that's terrible!"
So around the 425 I'm calling my running leggings skinny sweatpants, which b. just loves.
