what hurts the most....

another night is about to end and i am still thinking about my dog..I still cant get over the fact that i was not there for him when he needed me...I know i wont be able to do anything to keep him alive but just to let him know that i am also loyal to him until his dying hours... what hurts the most is wanting to be there for someone you love and care about in their trying times but can't...it hurts..even if its just a dog... =,C
