I have seen many resignation letters and mails saying 'goodbye' to loving colleagues. But, I love this one most. Bernard Sainte-Marie, a former banker at Lazard, lashed out at Bruce Wasserstein in an email message to his colleagues as he left the firm last week. His mail is an interesting mix of heart-felt messages and funny comments such as "I will be pursuing my career in the general unemployment line, as I am neither old enough nor wealthy enough to retire. I wish myself every good fortune in the future."
