Love:

When we start liking someone and it later developes to a love bond, we take care of other person and expect him/her to be in best condition. We make sure that we help and take extra efforts to ensure confert to the person.

I believe that only when we were truly in love, we take care of Oswald as well so that our love enjoys or company the most and we have each other's company  for longer duration in best possible way
