I rather be a second-thought than an after-thought.
The way I see it a second-thought is nothing but doubt. An after-thought is something you remember once it's too late to do anything. I much rather someone think of me with doubt clouding their first instinctual thought/want than someone forget about me until it's too late. Afterall one of my many great fears is being forgotten by those I chose/force myself to remember. I don't want to be forgotten. I don't want to have lived how ever many years in someone's life just to be forgotten. Forgotten like an old toy you once loved and promised to keep safe forever. Then again a lovely white rabbit once said, "sometimes forever is just one second." If that's true I don't want promises filled with forever because to me forever may be a century but to you it may just be a moment.
