[Grammar] Kimberly walked to Tim's house. She noticed Sue outside

[Nikitus]

Hello.

Are the following sentences grammatically correct?

"Kimberly walked to Tim's house. She noticed Sue outside Tim's apartment, walking impatiently, waiting for him."

Thanks.

 

[jutfrank]

Yes.

I'd probably use "pacing impatiently". Walking suggests that she is going from A to B, rather than what she is probably doing which is taking a few steps one way, then the other, backwards and forwards.
