From Arita: Mother of the Bride

I flew in a huge plane home from Philadelphia - sitting there relishing the fresh memories of my daughter's wedding. There were three seats on each side of the aisle and being a SWA flight, it was completely full. Guess what? Both the other women sitting with me were also MOB's - one also coming from her daughter's wedding Virginia (like mine) and the other going to her daughter's wedding in LA. The dates were consecutive weekends. What are the odds of that?
