The first nice, sunny, warm day of the year. When the girls all begin exposing their cleavage (aka T's). Also known as one of the happiest days of the year.
Is it T-Day yet? I don't think so, too many coats and sweaters are being worn today. What's the forecast for tomorrow?

Get the T-daysmug. The anniversary of recovering from an organ transplant and starting a new life thanks to the generosity of the Donor and or their family.
Two years post Transplant, the Transplantee held a T Day party on that date to thank all those that helped save his life and recover.
