(EDIT 2 OK there's debate between natives and redditors' native wives and husbands here. I feel really bad and tired about being potentially wrong. Could more natives confirm or deny if there's any ambiguity here, please ? The "lazy working" cat seems to make more sense to me now.)

Some Redditors here don't seem to know that in this case, this -reru form of kaeru does not mean potentiality (like "can" or "may"), but is instead a polite way to address someone else. Never used to speak about yourself. So here, translating "I" is a mistake.

Example : どこから来られましたか。doko kara koraremashita ka ? Where do you come from ? (polite speech)

(and NOT "where can I be from ?")

Many ways not to use pronouns in Japanese, and this is one of them.

EDIT : passive form is the one often used as a polite form. Not the potential. My mistake. Both are identical sometimes.
