You never talk about being a woman, because someone might notice that you're a woman, right? They might notice. Or worse, if you say "woman," people on the other end of the table think you're asking for special treatment, or complaining.
Nunca hablas de ser mujer, porque alguien podría notar que eres una mujer, ¿verdad? Se darán cuenta. O peor aún, si dices mujer la gente al otro lado de la mesa piensan que pides trato especial o que te estás quejando.
