Childish

Don’t call me childish when I’ve had a job since I was 16.  
Don’t call me childish when I pay all my bills on time.  
Don’t call me childish when my life is more together than yours.  
Don’t call me childish when you can’t even put dirty dishes in a dishwasher.  
Don’t call me childish when you throw a fit when you don’t get your way.  
Don’t call me childish because at least I have a steady job.  
Don’t call me childish because at least I know how to put dishes in a dishwasher.  
Don’t call me childish because at least I don’t spend all my money on drugs.  
 
Last time I checked my name was on the lease. You’ve lived here for five months and still can't afford to put your name on the lease.  
 
So who really is the childish one?
