Looking at the gravestone its easy to dismiss it as a crude mess. The writing is carved by someone who can barely write. The thing that looks like a smiley is supposed to be a skull and the x is supposed to be bones which is a very simplistic copy the usual decorations of headstones at this period.
Now think about what you are looking at. Someone who presumably was to poor to afford a headstone felt so much for the person that had died that they did the best they could to create one by themselves. They must have loved them very much to have done such a wonderful thing.
