Throwing himself a party is pretty sad.. but the people who truly care/cared for him won't be there, just superficial people, and that IS SAD.
I see his party as very...odd...selfish...but apparently I never acknowledged his birthdays in the past, and this is his way of taking care of himself. He threw me a huge surprise 30th and 35th party, but when it came time for his parties, I got the "Don't spend the money, I don't need a big party, just you and the girls". But obviously he was thinking another thing. Not fair to me, I am not a mind reader.
