And wearing bumblebee costumes.
Seriously though, many guys and gals who I know that are on the cusp of dating really have no concept of what marriage is. Many of the guys seem to believe it is simply continuing learning in yeshiva with the same chavrusa and same chevra, only now instead of his father paying tuition is is covered by his shver and meals comes from the wife instead of the yeshiva dining room. Many of the gals seem to believe that nothing significantly will change either. They will still go to class at the local degree mill or touro or still go to work and instead of going home to their parents they will go home to a new roomate called “my husband”.
