I see.  Supportive actions like... hugs and kisses and other social rituals to show your friend that you care.  Is that what you had in mind?

Hmm, do you have any advice in mind?  Do you know if they have experienced a serious injury like this before?  
If not, perhaps you could ask them what would help them feel better?

I'd like to soothe a friend of mine, who skinned their knee. Do you have any helpful suggestions?

Sounds painful!  How about some ice?  Would that help?  I think ice is the first thing people usually reach for.
assistant
Might be. They got the wound covered up and the bandaged. I wonder what some supportive actions might be for my friend?
