A Girl Transferred To A Public...

A girl transferred to a public school. They have a three-rowed rest room for girls. Nobody uses the middle stall of the restroom except her. She's wondering why she always feel there's someone touching her forehead every time she uses that stall. One day, she saw a janitress and asked her:

Girl: Excuse me, matagal na po ba kayo dito?
Janitress: Oo, bakit?
Girl: Kasi sa tuwing ginagamit ko yung gitnang stall ng restroom parang may humihipo sa noo ko...
Janitress: Huwag mo na lang pansinin yung, PAA ko lang iyon nung nagbigti ako.

Waah! Katakot! (@_@)
