We are all used to exchanging or returning goods upset when we couldn't or have to pay penalty We are typical not so tolerable for request to return your love (exchange for someone else) from others understandable our hearts are not the same some beyond repairable because feelings are not goods to start with but some think that way unconsciously We might hope for others more tolerable when we change our mind But we could all give the best wishes return more love to whoever changes his/her mind that could keep the nice memory alive not letting the future ruin your own bases The warm feelings of the past are valuable for your own sake not for bid like antiques(used but historical goods, except for writers who could make a book out it)
