Using experience to explain something is not virtue signaling. Virtue signaling is, for example, claiming that I am better than you because I drive an electric car to save the environment (I don't and it doesn't), or looking down on another because I buy all my clothes from the natural fiber store (again, I don't).
I don't know here you got 'bragging' from my comment. But I am not going to battle stations over it.
Heheh. Yeah, right.
