Is this really what love is, though? I mean, doing dishes for a sick friend or relative shows you care, but is the act itself actually love? Does anyone actually love doing dishes? You can not dislike doing them or even enjoy doing them, but I wouldn't say that's love. I would say that all the examples you gave show caring and possibly compassion. However, nothing says that's love. One could say they are done in love or you baked a cake "with love", as you either are passionate about baking or you care about the person getting the cake, but again, is that really love? What is love, anyway?
I think, in today's society, we use that word too loosely. We say " I love that movie" or " I love that song" or " he loves pizza", etc. If love is supposed to be this all-consuming aspect of life, none of those things actually qualify for the word "love". Yes, you can really like that movie or say that's the best pizza you've eaten, but it's not on the same level of love that you are to give your partner. To equate washing dishes to loving your significant other devalues your feelings for said partner. Yes, you may say you wash the dishes because you love your partner, but that's not why you're doing it. You care about them and their happiness. You are more than likely sharing household chores in order to show each other you care about the other person, but that's not showing love. Isn't love supposed to be much loftier and deeper than that?
I think there are different emotions that people mistake for love. If you think about it love can be both good and bad. You can say you love someone when actually you are obsessed with them and fantasize about them or come out with scenarios that never happened, but you convinced yourself they did. You can say you love someone, but it's a fleeting feeling not a deep everlasting connection. Is that really love or was that just sexual attraction?
I don't know if someone with a PhD can really tell you what "love" actually is. I've found the deeper in academia someone has become the more lofty their responses are and they are no longer looking at this through an every day human lens. They are looking at things to the abstract and things like true feelings, emotions, etc no longer have any meaning to them.
Hope this made sense. sorry for the book. Just general ramblings from a member of the peanut gallery. (BTW, Orwar gives great hugs. Though if more people knew that, he'd have to charge and there'd be a HUGE line. I hate waiting in lines. lol )
