If you get any social calls, I'll have to talk to the person and explain.

Victor was a good friend, but he didn't make social calls in the middle of the working week.

That was all right; she wasn't here for any social call.

Then, of course, he realized that they weren't here on a social call.

But it didn't sound as if this was a social call.

He could tell that she had come for some reason other than simply making a social call.

At any rate, I doubt that this is a social call.

His uniform made clear this was not a social call.

"Is this a social call, or are you here on business?"

But he was quite sure it wasn't a social call meant to welcome him to town.
