"I know... I'm a bad mom. The precious little boy I had is probably gone now. You have grown up without me, and we can't change the past.
In this very present, I have you, I have my dear grown-up son, alive and fine, and that's enough for me.
It's good, I'm happy, you will soon properly be twelve, and it will be fun~.
And even though won't do much as you like, it will be quite fun, and that I'm sure of~.
You will be going to your friend's house, again, with my two lovely daughters, so you better take care of them until you come back.
Besides, I have a faint idea about the thing you two are planning. And seeing this stubborn future daughter-in-law of mine, that one must be inevitable.
Huuuu... so, don't worry and just go~. We will do our best this time too~! Far better than your last birthday we celebrated~."
She was cheerful and I knew she would find out from the way the both of us had spent this past week.
