Give 'em a hug today.
This afternoon I'm attending a funeral for my 27-year-old cousin, the youngest of two siblings on that branch of my family tree. (He got frustrated, he got impulsive, and he did himself in.) My heart aches for his family, particularly for his older brother.
I'M an older brother, and I don't want to begin imagining what he must be going through. I will be seeing my brother today, and giving him a hug.
If you have a younger sibling, give 'em a hug.
