Get some fresh air.
I miss my mother every day, but maybe more so on Sundays. We would often call each other on Sunday. And of course, back in the days when we lived nearby, there were the Sunday dinners.
But I most miss my mother's advice. We didn't agree on everything; I hated that she watched FOX News too much. But she could tell just by hearing my voice, if something was troubling me.
So, now I have to try to imagine what her advice would be. Sometimes it's easy. Other times... I just wish I could pick up the phone and call her.
