Richard is still in lockdown ,he manages to casually mention it *sigh*. To cheer himself up he asks about Andrews film .
The student film is every bit as chaotic as you'd expect . The issue  seems to be mainly the conflict between the film being a group activity and Andrews struggle to work in groups.
However you have to admire his grim determination . 

The importance of optimism is discussed at length .

Blind optimism in the face of reality . Richard admires this characteristic in his partner ,as she goes about converting a spare bedroom into a guest suite.
No guests are due in the foreseeable future but that doesn't stop her . 

Andrew is excited for the new iPhone which is a surprise , the conversation is not what you may reasonably expect .

Richard feels that one of his gestures is out of date and has no meaning . Naturally he turns to Andrew for guidance ,You will all be better for what follows .
