I have 3 tattoos and they are all only visible to me. I get tattooed for me, not to show off the work to other people.
I don't have a "favorite memory". She is just an amazing human and I cannot express how lucky I am you have her in my life.
That is why the jackpot idea stood out to me.
Just wanted to see if anyone else has a better idea. I'm not the most creative person in the world.
