Sometimes; I try to be sure to make all the major ones

ASN: Sing for fun?

Sometimes - it must be in the privacy of my own home.

ASN: Orders a veggie burger?

Sometimes - or at least I have once; it was good, though, so if I go back to that restaurant, I will probably get it again.

ASN: Celebrate an uncommon holiday (such as National Sibling Day or National Read a Book Day or such).

Sometimes. It all depends on what you mean by "uncommon", though, or where you are, or even if you agree with the reason the holiday or occasion that is been commemorated. There isn't much call to celebrate Anzac Day elsewhere in the world outside UK, Australia & New Zealand, though France, & especially Turkey might remember it as well, and why. Not even every Australian celebrates Australia Day on 26th January. Some commemorate it as "invasion day, instead. There is even less reason to celebrate National "sorry" day, the day when Australia commemorates Aboriginal disadvantage, which is on May 27th this year.

ASN: Celebrate all your national holidays?

Always, in the sense that we have the day off and often have family and/or friends over on those special days, but in terms of planning big parties and invite the neighbourhood ... no.

Plant, tend, and harvest your own vegetable garden each year?

Never - I wish!

ASN: Drink hot chocolate in the summertime?

Sometimes. The summer weather in England can be rather cold and wet at times.

ASN: Vote in elections?

Always. Voting in Council, State & Federal elections, & in Referendums is a compulsory duty for Australian citizens.

ASN: Think very carefully about what you are voting for, & what the politicians on both sides are actually saying, in such elections?

Sometimes.

ASN: Burn candles on cold days?

Sometimes, though the fact that it's on cold days when I do it tends to be a coincidence. I just occasionally get in the mood to burn a candle.

ASN: Watch trailers for a movie you're already planning to see?

Sometimes. Usually I have to have seen the trailer before I decide.

ASN: Take silly photos of friends interacting with advertising posters?

Never. I think most of my friends ARE advertising posters!

ASN: Try to magically turn a stoplight green by merely pointing at it? And pointing at it? And pointing at it until it works?

I talk to them and try to explain why they should be green now, does that count? If it does, sometimes.

ASN: Watch YouTube videos about topics you're not actually really interested in because you like the host?

Sometimes. I watch because they look vaguely interesting, and I'm halfway through before I can tell if they are worth it.

ASN: Discover it is half an hour later than when you looked one minute ago? (happens most often at bedtime)

Sometimes, especially when I'm reading, which is always in the evening. Time simply flies by when one is reading. ♥

ASN: Have fresh flowers on your inside table to brighten it up, especially when in-season?
