Very important.
In fact, as a UNSW Arts student, it is part of unspoken degree requirements that I lounge about on grass for at least an hour each week, every week during semester. Minutes where I am sipping coffee count double (so I can sip coffee for half an hour and fulfill that requirement), minutes where I am reciting poetry or lounging about with other people count treble and there are also clothes multipliers as well, for instance - John Lennon glasses give you a x1.25 time multiplier.
I can't imagine what those UTS Arts kids do with no grass
I cannot fathom to think what extramural degree requirements they could possibly have.
Long story short, I love my grass. A lot. And damn anyone who takes it away from me! I am feverishly passionate about grass and indeed, have deliberated for some time on whether I should buy some for my own personal use at home - so I may extend my Arts degree learning by partaking in activities at home, that so happen to be part of unspoken degree requirements.
