'O' is for Outsider

There's this nice little family I know. Mother, father and two adorable young girls. Their lives are not perfect, but all said and done they look happy.
Ah, did you say they have problems, which family doesn't?
Despite it all is where I'm at.
My family, did you say that is my family? Really, how have I been so fortunate?
You see, sometimes, I feel just like an outsider. Only looking in.
