- I'll ask if I can help in any way so that he doesn't feel awkward.
- I will try to explain the matter in a way that makes it easy to understand.
- I will discreetly offer him help only after the discussion.
- I'll leave him to manage on his own if he doesn't want to ask for help.
- I will wait for the opportunity when we are alone, and I will ask him if anything is unclear to him.
