This episode is really touching and has a wonderful ending. Sophia forgets her anniversary and we find out that she is losing most of her memories. It really takes a toll on her and Dorothy. It's played for laughs, but has a real serious side as well. "I can't let this happen Dorothy.I can't loose my Sal, not again." This really lets you know how hard it has been to loose the one you love. When they travel back to Brooklyn we see the apartment that they lived in, complete with the new Puerto Rican tenant. The height charts on the wall, the old wallpaper are all reminders for Sophia, but they are not the heart that Sal carved on the back of the door that says Sal loves Sophia. Sophia swears it's in the kitchen and when it's not, she is really afraid that it's all over. When she goes up to the bedroom, she imagines Sal and has a very funny talk with him. He prods her into remembering.
When she discovers the heart on the closet door, her spunk returns and you know she's going to be ok. As the show ends we see the heart and it brings a tear to my eye every time:-)
