finding love can be difficult. when you do, it can be just as hard to hold onto. the perfect love is said to take time, patience and sacrifice. like a snail's shell, when you find love it will keep you safe through tough times and allow you to weather any storm. although it may be carried on it's back, the love is not a burden, but a virtue - it protects the shell that protects it, and in so doing they prosper together.
