Since that point, several presents had made it up there as well, john moving into the room as she negotiated her belly next to one large box about to be wrapped.
"Woman, what have I said about doing too much?" he asked, as stern as he could, but the words and tone were softened by a clear affection as he moved forward to take the paper form her hands.
