Describe a dinner that you enjoyed

Why do you think it was a waste of time?
my research didn't yield anything conclusive
I didn't receive any conclusive results
I didn't get the desired results
I didn't get the results I'd expected
despite the effort, I didn't obtain the results I had hoped for
nobody needed what I'd prepared (made, done)
nobody appreciated my work
my project wasn't implemented
the plan remained on paper
my startup failed in the first year
my startup didn't survive its second year
when I prepared a business proposal, the client said he (or she) was no longer interested
my boss told me he (or she) didn't have time to read such a long document and asked me to prepare a short summary of the findings
my problem wasn't resolved
I wasn't doing anything that would leverage my life or career
I had already made a budget, planned the menu, booked the venue and even ordered invitations when my friend told me he changed his mind and decided not to celebrate his (or her) birthday
