Slide Shows At Weddings-Why?

i dont like the idea to be honest... i think a wedding day is the beginning of a new life, and having all these photos of your past shown is highly unnecessary..... i think they should be celebrating where they are now and who they are with, not reminicising and putting a display about them in their past, it really doesnt fit in with the theme of marriage in my opinion, birthday celebration maybe, but wedding- nope.
