Do you have a sibling? What is the relationship like?
I'm male aged 19-22, I have an older brother about 4-5 years older (giving age ranges for better anonymity). Relationship is... not good (read: it's terrible, horrifyingly terrible, arch-nemesis). How about you?
Got an older sibling by 2 years. We don't talk weekly, but we are still quite close when we do talk. Always have been close. Never big fights and usually got along really well.
As kids we used to "manage a business" together (it was plushie based) - we entertained ourselves during long car rides with that business.
I get along really well with their partner, I am like a mix between the two of them. We can talk about everything. They called me when they had shit going on (like their gender), they took care of me when I was suicidal.
