catch me lying

i can never hide a lie as my mouth changes
the twitch of the upper lip will signal it all
and you would catch me lip nipped

my eyes twinkle then my eyebrows rise
and the cheek temples sharpen at the edges
while the mouth tries to stiffen the curves

it is clear in my facial expression.
don't even expect a word, as i close my mouth
and add pressure at the poles, eyes rolling.

expect my immediate hesitation though,
then the rosyness of embarassment,
and you would have caught me for sure.
