The Pigeon and the Pheasants
Once there was a pigeon who wandered around a pheasant coop, looking for bits to eat. It noticed that every everyday the farmer would feed the birds and shoo him away. One day the pigeon thought, I'll pretend to be a pheasant and get as plump as them too! He found some old feathers, put them on, snuck into the coop and feasted heartily. A month later the farmer came out to collect some birds for dinner and selected the pigeon as well.
Don't envy a person for what you THINK they have.
