Similar story with my in-laws other than the bugger off part. Really cool thing to do. Helped us a lot with a deposit for a house years later.24.
Started working one month before i turned 22, after studies. Had to pay parents a big chunk of my salary as Rent.
My mom went out and found me a place to rent, told me to bugger off now. Was saving for lounge suite, tv, and kitchenware, but with car payments and their hectic rent i was screwed. Man i was pissed.....
Turned out all the money i paid rent for two years was kept and they gave it to me. Said they knew i was gonna waste it so they kept it for me under pretense of rent, meanwhile they were saving up for me. When they thought there was enough for kitchen and lounge suite they kicked me out.
