just now, when i open the door(my house), i saw a cockroach(roach) on the slipper. i ran into the house to take a container and baygon. i went back to catch the cockroach but i cant catch, so i use baygon. when i spray the cockroach, it is at the edge. so it drop down to 7th floor. i from 9th floor run down to 7th floor to catch a cockroach.(i know im very lame. haha!!) in the end i left it outside my house. ZZZ.
