Tree swing? I’m afraid I don’t know anything about swings, is there another sort of swing that I can help you with?
assistant
bummer. are you sure?
user
Yes, sorry I can’t help.  I am able to help with computer stuff, physical safety, and improving your mood.  I’m just a little uncertain about what a tree swing is.

Hm. I’ve never heard of that type of swing. I’m not an expert on anything like that, but perhaps you could explain it more?
