I hid my real salary from parents? Anyone else did same thing?

I work from home and come from a middle-class family. I've seen my parents spend too much and going beyond their financial limits. As a fresher, I told them I earn only 19k, but in reality, I earn 39k now. I've also started investing a little. Just curious if anyone else has done something similar. Edit: right now i give them around 14to 15k monthly and have told them i will manage in 5k
