I thought they went to VISIT friends, not that friends came to visit THEM.
Both happened, reportedly. The family stopped by friends' homes to drop off gifts on the way back from dinner, and neighborhood children came to the Ramsey house earlier in the day:
10 Q. (By Mr. Levin) It was brought to
11 my attention fairly recently that a woman I
12 believe named Jean Fortier, F-o-r-t-i-e-r, for
13 the reporter, who are the parents of some
14 children who were over your house on
15 Christmas, and they, they, she, excuse me,
16 said that her children reported to her at
17 Christmas day when they went over to play,
18 they played with Burke but that JonBenet did
19 not play because she was sick. I hadn't
20 heard that before. Is that nonsense?
21 A. Absolutely. I don't know who
22 that is, but we had a whole parcel of kids
23 there all day.
