Lintuset

A life lesson about difference, in the first act the birds are fighting each other and then the bigger bird appears, which is a reason for mockery and exclusion from the group, he unintentionally enters the group but the birds that used to fight get together to expel him. Of the group, they just don't realize that it will be bad for them and in the end, who ends up being different is the one who used to be prejudiced.
