=)

anything that together with you for some time..
you sure will have feeling toward the thing...
when the time comes, the thing will disappear along with the sadness..

pets are no exception...
a pet that with you for quite a period...
you will also have the feeling toward it...
when the time comes, it will follow to leave, you will follow the sad...

I know the feeling, but still hope that you can refuel quickly escape that sad mood..
