I hate I do it. I was not born in Southern Cal in the 70s (where like originated), and I am no Clueless cast member.
I'm 23, and I still have not grasped the fact that when speaking there are natural pauses where silence is golden... I feel like (for example) I have to fill the space. I need to stop being a,
"You'll need, like, three tablespoons of butter" person
...And start being a,
"You'll need roughly three tablespoons of butter" person.
From this post on, I vow to start pausing more and liking less.
