If she had left some for her brother, maybe he would have been happier when he arrived home.
In the above sentence I know that
If she had left some for her brother
is a dependent clause.
I know that
when he arrived home
is a dependent clause.
It seems to me that
maybe he would have been happier
is also dependent!
Which begs the question: can you have a sentence made up of dependent clauses with no independent clause in it?
Can anyone enlighten me please?
