Ahhhhh semantics.
So hard to gainsay any of the above thoughts, and isn't that the point. Each must individually pursue life and love in a manner that makes one happy.
I only hearken to the thought that ones love for ones first child is not diminished by the love of ones second and subsequent children. You many even love them for different reasons but they are all beloved.
So why not open yourself to love from any, from every quarter... and why not offer it as well.
I think about how our society preaches that there is "one true love"... and if you have/had that and meet someone who captures your heart... does that mean the first love wasn't or is no longer a true love?
That, too me, seems cruel.
The above remark is not a commentary on relationships and loves that fail to prosper for other reasons... but if love is not truly an endless resource, something that can be shared with many, then what if you have not enough love in your heart for even the one?
Then again... maybe the tinman was lucky.
