It sounds like a fun holiday.Thanksgiving is one of the few holidays I care about, albeit it's a bit different now that I eat healthy and in moderation instead of just stuffing down whatever in ridiculous amounts. Going to the in-laws' for this one (will be the first Thanksgiving there since I got married; last Thanksgiving at their place was right before getting married).
In Australia it's socially acceptable to have the time off work without participating in the reason for the holiday.
Lots of people don't celebrate ANZAC day. Lots of people don't celebrate Easter or Christmas. Lots of people don't celebrate workers on Labour Day. Lots of people don't celebrate the King's birthday.
But we all take the time off work if at all possible.
