Ezri speaks and asks questions I struggle to adequately answer

Looking at some photos of a gay wedding with two brides in white dresses. Ezri asked what they were doing. I said the two brides were getting married to each other.
Ezri: Two brides!
Amanda: Yes, when two women fall in love and get married there are two brides.
Ezri: I know, but shouldn’t one of them get to be the groom?
Amanda: Well, usually we call the woman getting married the bride, but I suppose if one of them wanted to call herself the groom she could.
Ezri: That’s good. I would want to be the bride.

E (sounding a little exasperated): Ivan, I need you!
i (bounding towards his sister): I am right here. I am right here, Ezri.
She needed him to help her carry stuffed animals upstairs to the pet salon (bathroom).

Ezri asks questions that are hard to answer and they are never the ones I am prepared for. I try to answer them.
1) What is a church? We are secular. She doesn’t have a church, so how to describe it – the building? the faith community? what faith is? why there is more than one? what a deity is?
2) Are there still pirates? Her vision of pirates is Captain Hook and silly, scurvy seadogs that never truly existed outside of media and stories. Piracy happens today. There used to be sea going pirates. The whole thing was a tricky conversation that boiled down to the historical pirates that inspire the Disney show Jake and the Neverland pirates do not exist, but piracy still does.
3) Who will live in our house when we die? This one wasn’t that tricky to answer because I don’t know and won’t ever know, but it started a discussion of death as a separation from knowing and I still don’t know exactly what gears I turned in her head about what it means to die.
4) Why is it bad to be old? This question was asked after a discussion of how it is not nice to say to be “wow, you are really old” which she had done. I don’t believe it is bad to be old, but culturally it is not nice to point out someone’s age. I think I said something about how we avoid talking about certain things and tried to explain taboos and included some ramblings about how we don’t show our underwear even though we all know people wear underwear. So, sure you are going to notice people’s wrinkles and know they are old and they know they are old, but we still don’t mention it.
