How I love
I look at basic science for the answer. The basic biological manner of an organism is to stay , thus reproduce. I go a step further and say human nature mixes in with that and next thing you know, a person has this fear of being alone. They desperately find connections and try to relate to one another.
This is where I come in.
Knowing that in relating to others the best gift I can give is to listen. I have this saying that the world does revolve around you. Every person living really only has their own experience to use as vantage point. On a personal level it's hard to care about anything other than what we want because it's our lives. As you can imagine in a situation like this, empathy puts love on top.
I am willing to do things like leave the toilet seat up and give nightly back rubs if that's what he expresses to me. When you listen you learn that his mom made the best peach cobbler and you surprise him now and then with it. Making people feel good is what love means to me and I do that best by listening until I know them well and doing the little things I interpret will make him happy based on what I heard.
