spending a lot of time together

1. DEAR ABBY: My elderly father has been a widower for many years. His neighbor, also his age, recently lost her husband, and they have been spending a lot of time together. He takes her shopping, she cooks for him, etc. My concern is twofold: one, this woman is not in good health, and I can't bear to see Dad heartbroken again when she dies. My second concern is the woman and her husband never even invited Dad over for a cup of coffee after Mom died, but now that she's a widow, she all of a sudden wants to be "neighborly." I'd like to ask her why. Would I be out of line? -- LOOKING OUT FOR MY DAD

2. DEAR ABBY: I was recently invited to a relative's home because my nephew was introducing his fiancee, "Macy," to the family. I asked my nephew what gift Macy might like, and he suggested a sweater and told me her size. I bought her a lovely one -- at least, I thought it was lovely.

After Macy tried it on, I was shocked when she handed it back to me and said she didn't like it. I couldn't exchange or return it because it had been purchased from a store where I live, and this store doesn't have a branch in their state. I took the gift home with me and got a refund. Now I don't know what to do.

Because Macy gave it back to me, does she forfeit the gift? Should I send her the amount of the store refund? Do I owe her anything as a substitute for the gift she refused? She will be a part of our family, and I need to know what to do if this happens again. I'd appreciate your thoughts. --GIFT-CHALLENGED IN IOWA
