To love, is to act without a goal for oneself, or even to give, without gain. This takes many forms. Showing an opponent where they are open, so they may correct it. To help correct something that may hurt them, or even giving someone a dollar. Love is not sacrifice however, no matter how similar it may seem. Sacrifice implies you are giving up something that was yours to give away in the first place. Furthermore, as one 'sacrifices' they give up a perceived something, but in truth, they have two options. They may put their action on a pedestool, and breed a kind of resentment for the recipient, or they may let it go. After all, while they may be giving something up- They are gaining love.
Give something away soon, and by all means, forget about it.
