Just a random post based on a conversation i had with someone a very very long time ago:
Cats dwell around in the drain. They catch bacteria and their fur collect dirt and stuff. Sometimes they make annoying noises and sleep on people's cars. I find cats cute. I sometimes dare to touch them despite how dirty they are and felt fascinated at them.
Cockroaches dwell around in the drain. They have mechanisms to "reject" bacteria. According to my dad, the bacteria-occupied part of cockroaches are just their legs. They are mostly silent and sometimes randomly end up somewhere in people's houses. I feel more disgusted at them and think of them in horrible manners.
It's weird how similar these two creatures are, yet form such different impressions in my mind. I'm guessing it's instincts inserted into our minds since we were born.
