my parents put my stash back??

okay hi so i bought a bottle of benadryl + robotussin and i had put them under my pillow. i come home and they’re gone from my room and are sitting on the table in the kitchen. neither one of my parents mention a word to me, and i come back home today and my dad put both of them back under my pillow. i’m genuinely so confused??? like they know what it does bc they found me high in 2022 from benadryl. what’s yalls opinions on this im so stuck rn
