So when I study Bio chapter Inheritance and Variation, I learned that we have dominant and recessive traits. Teacher asks all of us to roll our tongue and it turns out that I cant roll my tongue. It is something that we can learn because its in our genes. So I have recessive traits, so what?! My friends that can roll their tongue are showing off in front of me. I feel like cutting their tongue whenever they did that. Thank God I still have humanity deep inside my my heart, so I didnt cut their tongue. Well not yet, if they keep on rolling their tongue in front of me I will cut it.
