I never voted, but I admit to suspecting it was just Hooman playing a prank.
Also, that hint is very obscure. All it tells us is that Hooman has a sister and that she did a very interesting tree decoration this year. Whatever can be extrapolated from this remains only a theory.
Hooman, it depends on which people chose that option. We do have some people around that would have picked that choice just for the laughs.
