I am having 3 long tables at my reception. One table will be my family, one friends and one fiance's famy. However, friend table is not full and fiance's family table is over fully. So....do we put some of his family at friend's table OR do we just take some of the younger of his family (teenagers young adults) and mix them in with friends? I guess I am asking if its ok to separate families. SO if I have a family of 5, is it ok if we take the oldest kid who is 22 and put her at the friend table with younger people and leave her parents and younger siblings at the "family" table
