Very lucky.
Absolutely.
My brother is a year older than me, and growing up, he beat up on me fairly often to the point I avoided him.
One of the great things about getting older, is all that stuff as kids makes no difference in the end, and he became my best friend, on par with my best friend who went in the Navy with me and who I also see quite often.
My brother was the Best Man at my wedding, and in his historically long toast, he characterized himself as “The Freddy Krueger” of my childhood!
And I get to hang out with him once a week!
