Started from my childhood time & I can simply say I'm growing up in age with it...I'm someone that hate anything dirty around me,not that I'm born in a Behind home but I can't just sit a minute in a dirty environment.
Observing myself of recent,I consciously noticed myself picking up dropped food on d rug into my mouth, why ? Just because I see those drops as dirt while I'm eating,now it has turn to an habit while eating indoor.
