sys questioning shit

so in trying to figure out fur sure whether im actually a singlet or a system ive been doin lil calls back to the mind 

hittin em with the “hey its juice is there anyone else in here”

and im not saying i havent heard anything back cause thatd be a lie

but like if i did get a response how would i know its not just my brain providing adhd noise or me replying unintentionally . theoretically.
