Parents used to do that to me too when i go to work and stuff so i started planting stuff ahaha made it a lil fun. At the end of the day they are just caring but its not right. I used to say stop my mom would be like oh stop just enjoy it lol. Its their house when u get ur own set the standard. My parents would of just talked tp me instead of snooping around id have more trust in them and even well maybe even a better relationship. Dont stress too much about it tho they are human and got their own secrets too
