What a day

What makes for a good birthday?

• Cambridge in spring
• everybody calling to wish a happy birthday
• having a reason to go to Dickson Brothers
• spending the day working on some research at Petsi Pies
• understanding a proof by Saharon Shelah
• finding out that the most recent “bug” on mathblogging.org is not critical.
• sitting in the garden behind Barker Court
• simplifying an argument of Shelah
• being off for dinner with friends

Nice.
