parents misgendering me awkwardly

back home for the holidays and my parents keep calling me “she” but it seems really forced and awkward. i haven’t commented on it at all or even asked them to call me he but obviously i do not look like a woman anymore and they seem to feel guilty about still calling me she. my mom asked me not to get offended bc they’ve “known me as a girl for 20 years” but it seems like it’s getting increasingly harder for them to pretend i’m still a girl. i think my strategy will continue to be not saying anything and letting them feel bad on their own. i know who i am. i know that strangers in public do not see me as a woman.
