On day 2 of riding my then new to me hybrid, I made an unplanned abrupt stop.
I did a nose stand with the rear wheel about 3' (I wasn't looking back at the time) off the ground.
I kind of stepped off to the left and the rear wheel came crashing down at about a 45 degree angle from vertical. (I was basically holding on to one end of a large hinge with the other end under the influence of gravity)

It knocked the wheel out of true enough that I had to release the rear brake to ride home.
Simply put- The factory spoke tension was extremely uneven.
So, sometimes it doesn't take "That much" to knock a wheel out of true.

I ordered my spoke tension gauge the same day.
