How’s your relationship with your sister now? Do you remember anything ftom when you were 2? I doubt you scarred him for life unless he’s reminded often enough. You did the right thing in accepting responsibility and apologising and you’re clearly a good person.
I’d let the weight of that memory go if you’ve worked it out with sister.

Comfort zones…. Pfff. People related. I said in jack thread over there about pushing myself for scientific experiments. That’s me pushing myself outside my comfort zones.

It’s was said to me once about how stress is like a rubber band and when it’s not stretched then all well and you gotta stretch it a wee bit and it feels tight and uncomfortable but once you realise that stretch isn’t breaking it then you can’t stretch it a little more and then more but if course there is the snapping point but you get a fair amount if stretch out of it before that happens and you never go straight to snap the band. Stretch it gently.
