Or you could be D Marcus having dinner with Mark, telling him how you are looking forward to your next big adventure, one that FB is not doing. Mark who values you and wants to keep you asks why not do it in house. It will essentially be like starting your own company from scratch, only you won't have to raise money, hire employees, etc...
