I would erase my lack of understanding towards what my mother has been through, and how she fought for her children.
I may have been a child, but I also was not there for her when I believe she needed it, instead, as a teenager does, I was against her in many things, not knowing how hard she fought for me, what she gave up, what she did and had to endure to give me a better life.
I would erase my attitude towards her, I would erase me behavior, and I would erase my words.
I would replace them with understanding, empathy, love, and everything she deserved to hear from someone she fought so hard for.
