You'd think it'd be more subtle in case it does get mis-delivered to ppl with kids (if not just the brand name that ppl wouldn't know unless they're familiar like bad dragon)
Imagine if there was a plot twist of her not being a real deliverer and somehow just had the uniform and waits for the “real” one to leave so she can grab the package and knock as an excuse to talk to the boy (tho guess that wouldn’t make sense if every delivery person knocks and the issue with the wrong delivery but I guess there could realistically be “usually another person does this route but I offered to take it”
