happy anniversary oma and opa

well, my parents celebrated their 31st anniversary last week (may 12) and i was trying to explain to jacob what an anniversary was/meant. i told him this is a special day where we celebrate the day when people get/got married. since he recently went to a wedding we had already explained married to him (meaning 2 people who love eachother very much and wanted to live together for ever and be together). well, he explained to me that oma and opa are married to eachother, grammy and pa are married to eachother, mommy and daddy are married to eachother, and that he and sister must be married to eachother... 'cause they like to play together. as i told grandpa that later on he(grandpa) assured me this must be the case, becuase it's always good when a mommy and daddy play together... then we have grandkids. ;)
