Yes, big hearts can be a burden, I find myself having a lot of difficulty where I live (Toronto) because it's a big city, and people don't seem to care about much. There are so many homeless people that get ignored- it takes me forever to get to work just because I won't ignore them. (I don't always give money, but I at least acknowledge that they exist and apologize that I cannot give them any change)
Fortunately, my boy has a heart that could crush a building, so I'm well taken care of in the kindness department
It sounds like you know the burden from experience, do you suffer from cardiac gigantism as well? :)
