sense of entitlement

It confuses me on a daily basis the sense of entitlement some people have. Why in the heck would I want to bust my ass for someone who happens to be the laziest person on Earth!?!? I don't! NO ONE WANTS TO HELP SOMEONE LAZY AND USELESS!!! NO ONE! This person I am referring to comes in late or calls in sick weekly but is the first one to leave for the day because she is "so busy". She is also the one telling anyone that will listen their entire life story if they let her. I don't know why I waste my energy plotting her death, but I DO! lol. I can't take it!! ok- I am feeling much better now... ;0)
