I go back in, pick him up, snuggle him on the couch. Apologize. Tell him I love him. Tell him that I have hard times too. Read some books. Apologize and tell him I love him again.
On these hard days, sometimes I have to just try and see some of the details. Details can break apart some of the drudgery, letting in bits of light that awaken me. Details can be reminders of the here and the now. That this here and now is always changing into another here and now. Perspective. The present is forever creating itself and this, too, shall pass.
