[Grammar] Casual call or Casual visit?

[Rollercoaster1]

Hello,
I have just read a sentence on an English website, I just want to confirm if it's a typing mistake in the sentence below:
I dropped over to see her because I knew she wasn't feeling well. (Paid a casual call).

 

[Tarheel]

I see nothing unusual about that.

What do you think is wrong with it, Babarbutt?

Is there no difference between "call" and "visit"?

 

[Tarheel]

Is there no difference between "call" and "visit"?

Not if you're talking about seeing somebody in person there isn't. Example:

Barb: I'm going to call on Susie to see how she's doing.
Sharon: Can I come too?
Barb: Sure!
