はは, かあ

The sun lets out one drop, and then another drop. The drops dance together in the air, combine, and when they hit the ground, up sprouts your mother!
Suddenly your mother points at you and laughs, "Haha (はは)!" She keeps laughing, haha haha haha, over and over. You start to feel uncomfortable.
