What is your biggest regret in life?

Mine is,

Why yesterday I couldn’t be a little more patient, more relenting, and more understanding.

Though it only takes a willingness for me to talk more pleasantly, wait more calmly, or even to enter her world.

But unfortunately, I didn’t know I could have that choice before.

Then the regret continued,

If only she had met me in today’s version. It would have been better, and she would have been less lonely,

because we could have talked a little longer.
