Be the Gentleman and help her to her feet

Harry helped Tonks to her feet and wrapped a rug around her until he could conjure her a new skirt.

Tonks sat on the couch, still flushed with embarrasement and asked Harry if she could go change somewhere more private.

Harry heard Tonks **** and then start crying, just as the tap turned off.
