ASK Lavender Patten what her Christmas wish is and likely as not our caring First Lady will say that it is that every child in Hong Kong gets a gift of a toy this holiday season. So yesterday she was over at Swire House to launch the Spare A New Toy Appeal (SANTA) and hope that we will all get into the Christmas spirit of giving and help to surpass last year's total of 12,000 new toys that were donated for distribution to the children's homes of the territory. Organiser Irene Tulloch said: ''Some of the children who will receive these gifts are disabled, while some others are abandoned. ''They are used to living off cast-offs and hand-me-downs. We believe they deserve better at Christmas.'' When we mentioned SANTA in Keeping Posted yesterday we gave details of the seven collection points that will be in operation in Kowloon and Central between now and December 18. This brought an immediate response from Sha Tin resident Gillian Poon, who wanted to know why no collection point had been designated in the New Territories. Gillian said: ''I'm sure that, like myself, many people would gladly drop in a gift when they were out shopping.'' We contacted Irene, who told us that, unfortunately, SANTA had only one driver and van (What - no flying reindeer?) and the poor guy was kept fully occupied getting round the collection points already assigned. But if there is an individual or even an institution like a hotel (Regal Riverside and Royal Park - are you receiving us?) in the New Territories who would like to put up a collection point and arrange for the toys to be delivered to SANTA's Swire House base in Central, they would be delighted. So who in the New Territories is willing to play Santa to SANTA? Irene is waiting to hear from you on 869 4364. PS: There are only 25 shopping days left to Christmas.
