Sara, the daughter of Harry and Laura, worked on a cruise ship for ten weeks during the summer of 2021. Harry was secretly jealous of Sara because she got to live a very glamorous lifestyle. In particular, she traveled to exotic Caribbean locations; slept for free in a cabin that customers paid $2,700 per week to occupy; ate fabulous breakfasts, lunches, and dinners at no cost whereas customers paid $900 per week to taste those delights; and received $400 in spending cash each week.  

Would all these things be included in gross income for 2021, explain why or why not?
