After my husband died suddenly from a heart attack, my world crashed around me. I was overwhelmed (不知所措) with the

小题17:
his duty to take up his position by the front door and remained there until the morning.
Each week, between German’s visits, I grew a little stronger, a little braver; every weekend I enjoyed his

. Then one Monday morning we
