You took my first step
And showed me what I need to know,
SD-JEM's official lyric explanation
As children we grew up really closely with our grandparents. We were always around them as much as child would be with their parents.
We learnt so much from them and they were such hard working people, growing up themselves. They were such a great example to our whole family, that we learnt so much from them.
So, for me, that lyric was to say how thankful I am and how much I appreciate everything that they taught me, in my life, before they moved on.
