I didn't know who

 To call To cancel that ride 

Saturday I get a message

 From the ride service saying they would send an Uber  

So the doctor called Friday

 To reschedule but I had to cancel because I wasn't gonna be able to change the ride time 

My i00 ride

 With motive  care which is probably a made up name because you told me a different name at first 

No ride 

No care 

And God only knows who that man was 

Trifling

 Very 

Who paid

 For this ride 

My ride

 Was one way 

The ride service

 Arranged a Uber for me to my doctors appointment 

Did the truck have a

 Sign saying Uber 

I'm gonna need a rock polishing kit
