From the current events, thus far I've learned:

-- It's useful to have a tractor in an emergency situation. Sometimes you get a free tank to take home.

-- Tactical jars of pickled tomato can be used to take down drones.

-- Alright, here's a serious one. (Had to lighten the mood first, because it's just so terrible.) Once you leave your house, what you take with you may be your only possession for a while. Woman runs to the air raid shelter (with her child & dog???), and from there she has to head directly to the border to avoid getting shelled.

-- Race can surface as a factor when you're a refugee, even if things seem OK during peacetime.

-- Your preparation may not matter that much if you decide to join the fight.

-- You only have today. I'm seeing more than one couple getting married in uniform. Peacetime may not be that different from wartime. You never know.
