#### Critic

We Uber drivers never know whom we’re going to end up with as a passenger {--in the same car--}. 
One day, I was driving over a new bridge, the design of which was very {~~confusing~>ugly~~}. 
Completely confounded, {==I muttered==}{>>Actually I said it out loud<<}, “I’d love to meet the {~~genius~>retard~~} 
who designed this mess.” With that, my passenger {==extended his hand in my direction==}{>>I thought he wanted to choke me<<} 
and said, “Well, today is your {--*very*--} lucky day. My name is Mike, I work for the county engineer’s office, 
and I’m the {==genius==}{>>obviously an irony<<} who designed this!”. Surprisingly, he still gave me a tip {++**of 2 dollars**++}.
