I've been great!! And yourself?
Unsquaring yourself can be troublesome but I wouldn't say disastrous.
You can open people (even trained people) up by using angles
Been doing well Haven't trained with the sifu in a few months because I'm goin through hard times but other then that...Life's treating me grand.
I can see your point about becoming unsquare but it goes against the principle and opens up opportunities for an opponent to take your line. There's no true benefit from not remaining square. If you have to do so in order to perform a specific attack, you may want to reconsider. The more you go off your line now, the more you have to correct later.
I know what you're saying though. Every circumstance is different and may require you to break the rules. It then comes down to how nimble and agile the practitioner is in order to correct that situation.
