How do you measure love?

In the movies Brothers the Mother is explaining how you can really tell if a man loves you. She says, if he gives you the last bite of food that you are eating together, then he loves you.

I don’t believe that, but let’s look at that concept. What do you signify as a sign of love? What is it that you do ONLY if you love someone? I know that I am in LOVE with someone if get me to go to watch a movie that I refuse to watch. Or, if there is something that I am 100% against and they get me to do it anyway, then I know love is involved. But this could be different for everyone. 

Here is where confusion sets in, you think that someone loves you because they let you eat the last piece of food, but they show their love in another way. They can eat the last piece of food and it is not because they DON’T love you, it may be for another reason. 

I am not a big talker on the phone. I will text more than I will talk. I like being in person more than talking on the phone. Someone may think that I am not feeling them because I do not talk on the phone with them for hours and hours. Or someone might not think I am interested because I only text once a day or once every other day. Other people may get another feeling. They might think because this person texts them every day, then they really like them.

What do you do for someone to signify your love? How does someone know that you really love them? What do you want someone to do for you to show you that they really love you?
