Found the following letter between the floorboards. Sidewalk and houses

Dear son,

I’ve been staring at this paper for a long time and don’t know what to write.
You’re good with this sort of thing, but I’ve never been able to, you know, talk about those things.
Do a damn good spreadsheet and balance the books, sure, but numbers are easy.
I’m sorry if it ever came across as if I didn’t love you or weren’t proud of you, because I was.Know that I always was. It’s important that you know that.
We’re very different, you and me.
I usually didn’t understand the things you were into, but that’s okay.
All that matters is they meant something to you.

I hope this letter is coming across as I mean it to.
I was happy we were able to work together and that I was able to see you stand on your own
and become a man.
And no matter what you may think, you can and you are.
You’re stronger than you know.
I miss you, son.
Take care of your mother for me.
