I don't know if any other trans masc ppl can relate but or have had a similar experience. Im NB and tend to dress a bit masc.
Ive had a lot of older sisters mistaken me as my mothers son instead of daughter. Like they would go "Ah! Es su hijo?" (Is this your son?) And each time it would fly over my mothers head (I don't know if she intentionally denies or genuinely didn't hear them Im a lil sus cuz it happened twice) And she would go "ah yes this is my daughter!" And the older sisters would get awkward like "😅Oh! Your daughter is very pretty-!... "
I dunno. Don't get me wrong. This religion is very transphobic. But I find the older ladies first response to my appearance oddly euphoric. Especially cuz I was feeling very dysphoric those days.
