Well, my brother phoned me unexpectedly this evening to see how I was (I've been off sick with a virus for a few weeks). He said "Are you okay?" and I answered with a maybe-yes-maybe-no kind of yes. So he asked me what was up, and I just found myself telling him "I've got some really intense stuff going on to do with gender, actually."
We didn't talk about that much, we moved on to other stuff, and eventually to him repeating his offer to help me move house next month.
And then he said "...I just want to give you any support I can - including for any kind of gender transition thing you might go through..." I was gobsmacked - I told him "I have no idea what's going to happen, anything and everything might happen" and he replied "I've known that about you for some time" - I said "what, the gender thing, or the 'anything and everything might happen' thing?" and he laughed and said "both!"
I'm astounded - partly by what he said, and partly that I just came out and told him. I've been inclined more and more over the last few months to takes risks in communication, but this was a real surprise. Me and him, we're all we've got when it comes to family (we don't have anything to do with our dad or his lot any more). I've supported him through a lot when he was pretty wobbly and low in confidence (after 35 years stoned, which didn't help). And now he's cleaned up his act and is giving me support, and that's amazing. I thought I'd be afraid of telling him, and I just wasn't any more - we trust each other. Cool!
