So I know it is tradition that if you have a sister she is included in the WP but my sister is only gonna be 13 by my wedding and everyone else will be in the 20's and I even have a lady in her 50's.... I want us to be able to goof and joke and have fun without worring what we're saying... I know I have to include her but I don't know what I can have her do...
Any helpful suggestions?
