As the eldest daughter, I've taken care of kids since I was 3.
By 15 I was leaving cheer practice at 5 to oversee homework, enforce bath time, wash uniforms in the tub, dry them by the fan, clean the kitchen, do my homework then go to bed to wake up at 6am.
I called in twice last year, and this year I took 2 three week hiatuses and called in at least 25 times excluding sick days and vacation. smt i been tired all year and still tired.
