Bought medicine to help boost my immune system .

Hello all. I have a small rant. I had medicine delivered to my house from Australia. It’s medicine to help with my immune system. Don’t worry I read everything about it first before purchasing and read reviews and most importantly, it was recommended to me. and omg when I came home my landlord had opened up my package. Who knows what she did but do you think it’s fair that she literally looks through the mail I recieve? I am moving out in 2 months or maybe even sooner. That’s why I got 2 jobs. I don’t appreciate her going through my mail at all. I don’t look through her stuff. Clearly she wanted to be nosy which is very sad.
