Analysis of Forgotten Birthday

I never knew your birthday until you passed away
Never had the chance to ask if you were able to stay
I don't remember much but I do remember some memories
Nothing to smile about since they aren't of you and me
We weren't as close as you may of wanted through out the years
It was probably why I didn't cry so many tears
I can't argue since you were always there for the grand kids
Just wished we were closer and maybe just maybe you could of given more than you did
You see I'm not trying to say you weren't there when you were
I'm just pointing out that part of my memories are just a blur
You raised us the best way you knew how even if it meant for memories to disappear
I've learned the hard way as you raised us through out the years
Don't get me wrong cause no matter I did have the love for you that maybe I didn't show
Just wished we had more time before you had to go
Of course we butted heads and maybe I remembered the wrong memories
But they were the ones I remember as they were the ones that was given to me
As I remember to wish you a Happy Birthday
I'll try and remember to remind you that it wasn't you that couldn't stay...
