It seems so. I must have been spared some of the strangeness, but what little I've heard about speaking to those who have been here longer, it was particularly strange. Nothing like this has happened before.
I see a wide manner of strange things, mostly by form of flora. I did notice a rapid bloom of tall orange or red flowers. I'm not too familiar with names, so I'm afraid I'm not aware if they are native or not. I assumed they were weeds since the blooms didn't seem to last very long.
I suppose...they would all be American, then? Since it's an American holiday, correct? The concept likely is weird to them not to celebrate as it is to us to see a big deal made over it.
And yet you're planning a dinner! I would be delighted, though, provided I may bring a guest should the need arise?
