Smarie...He doesn't want you to take a job where you will have a social life and do some fun things.....and he doesn't like it that your sister will be there
He wants to clip your wings...so you won't be able to fly....
Worst of all....you are an extrovert.....how cruel....
A sad bird with clipped wings, passively sitting in the corner of a cage, even though the cage door is open......
