saying goodbye

the hardest ..saddest part of leaving my job...was saying goodbye to the clients and knowing i would not be seeing them again... they tell me have a good weekend and see you on monday and i cant respond :(  i wish i could make them understand..but maybe its better that i cant..maybe in there world there is no such thing as goodbye..and they will just think that they will see me again..that i will show up one day..that i will return and pick up where i left off with them...and it hurts..i can put on a brave face..but it hurts.. :(  maybe its better i wasnt able to tell them goodbye...
