Something like this happened with me the other day, too. My father was telling me, 'to be honest, I never really considered you very masculine, or my 'son', just a tomboy.' A few minutes after that he became busy with a conference call from work- while he was occupied, my phone started ringing(it used to be his work phone, so I sometimes get calls from people looking for him) and there was this guy on it asking for my father.
I told the guy, sorry, this cell phone isn't his anymore. 'This is his... Uhh, child,' I said. I said CHILD, not daughter/son. The guy tells me that's fine, I'll just email him instead. 15 minutes later, my dad starts laughing to himself. I ask him, what? He says, 'I just got an email from human resources stating that he tried to call, but got ahold of my son instead of me. My son?'
That really made my day. It felt like such an honor to be considered my fathers son, especially through hearing my voice over the phone.
