I don't expect him to ask permission to go out.

But I do expect him to leave word downstairs of the time at which he is likely to return.

When he did come back, after an absence of some hours, I naturally asked for an explanation.

Would you believe it?
he simply informed me that he had been away on business of his own; expressed no regret, and offered no explanation--in short, spoke as if he was an independent gentleman.

You may not think it, but I kept my temper.
