Life is a strange and wondrous road. You meet people and you pass them by without a second thought of how long you will know them. Once you are further down the road you may forget about them or sometimes you will bring them along for the ride. If you're lucky, maybe you will travel down the path with them until their destination and have known them well enough that you are willing to let go. Sometimes there are unexpected stops, sometimes there are accidents down the road. Get to know your friends and acquaintances. Who knows how long they will travel with them until their final stop.
