order delivery status

Hi Meh! - Today (3/21) I got the first delivery status email for the underwear I ordered. The expected deliver date is stated as yesterday (3/20). Now, if the expeditiousness of my underwear delivery is an issue, I got bigger problems. So no prob on the tardiness. If, however, you possess a Time Machine, why are using it to get my draws to me in the past? And if yesterday me doesn’t like the way they, say, hug the jug, who does the return, me in the past or me in the present? And if the past me returns them, then will present day me even be sending this message? It’s all very meta.
