3 changes into 7

Friends from Evanston came over to visit. It is so much fun. Obviously we are aging, otherwise how come we keep looking back to the old days? He said"when i went to the airport to pick you two up at the end of 2000, there were only three of us, but now, we are 7 here.." later, I thought to myself, actually, now there are 8 of us, they are expecting another one. Oh, time flies...
