Message in a bottle

So i just finished reading "Message In A Bottle" by Nicholas Sparks.

Sparks usually writes on love and like all romantic writers I find him a bit unreal- perhaps because I haven't experienced true love in my life so I dont always get this stuff. I read it regardless to transport myself into a world different from my life.

Anyway I really liked this book. It had a good message- that one can get past grief of a loved one and be able to love again.

My concern though is - does a person really have to love One person at a time? Is it not possible to love more than one person? Just thinking.

I won't say more to spoil it for anyone who wants to read it.

For anyone who has read - please feel free to share your comments

Also - as a child who wanted pen pals through writing notes in a bottle sent out in the sea - I found something really soothing about this. Part of me still wants to do it, however out of fashion... haha. Maybe one day!
