Ohyou. :3
Imagine life as....a salesman. (I use this metaphor a lot

) Each morning, the same salesman comes knocking on your door. Each day he offers you a new product. Each day, he comes with a broad smile and a clean suit on. Its your choice, though, on how you treat the salesman. How you interact, if at all.
If you slam the door in his faces, chances are he'll get the idea, and leave. Maybe he'll call on the phone. Maybe some other agents will call. Maybe not. But each day, the salesman will be back, bright and early.
One must ask themselves, what should I do? Each day, perhaps, he'll return, kind and cheery, no matter what you do to him the previous day - short of killing him, of course! - and each day, perhaps, him and his team hold a number of products for you to view. Maybe buy. Maybe only get a free sample. Maybe passover. But how will you know what you want, if you merely slam the door or hang up the phone on them?
Some people reject the salesman, and push him away. Others embrace him, and see what he and his team have to offer. Are you really losing anything, though, by hearing what they have to say? After, they may persist, but one day, eventually, they'll stop coming. And what will you have to show for it, but an empty room?
Hm. Just a metaphorical thought. Very simple, find out what it means (No, the salespeople are not stalkers. /metaphor4life)
Hope this helps
