In fact, nobody has only one specific feature. But if I have to choose a word for myself, I select the word ' Meticulous' . Meticulousness is my distinct feature. It is my obsession. For example, when I wash my hands , I soap them at least five times. Being happy while cleaning, using Domestos all the times , being addicted to the odors of cleaning materials ... I don't know whether it is sickness or not . It's up to you ! :) :)
