4 months old

On Sunday my big yellow birthday balloon turned 4 months old.  That is so rare for a balloon.  With this kind you usually expect a month or maybe a 1 1/2 months, but not 4.  I really don't think it will make it until 5 months.  I'm just hoping it makes it through the weekend.  I inflated it the day I started to move stuff from the old space to this one and it's been in the window ever since.
