Meticulous

I'm usually the last to make it

The slowest in a group

Got an extra minute? I'll take it!

I'll even jump through a hoop

I grew up in a military family

And on military time

My mother, father, sister, and me

We may share blood, but come from a different temporal line

I am perpetually late

Leaving behind a meticulous trail

There is one thing I am punctual at -to  procrastinate

But even that at the pace of a snail
