WHAT did amahs get for Christmas? Well, after some research among the Filipinas down in Central on Boxing Day, we found that their Christmas gifts from their employers ranged from a return ticket to Brunei to a sweet nothing and no day off either. Connie counts herself as one of the luckier ones. Not only did she receive a watch, but she also, most important for her, was given two days off to enjoy her Christmas holiday. ''We went to Calvary Fall Gospel Church for most of Christmas Day, where we sang carols and songs. Then we had dinner and slept there overnight,'' she said. ''It's the first time for a long time that I've been able to spend a night away from my employer's flat; it was very refreshing.'' Her friend, Elvie, a trained midwife who arrived in Hong Kong six months ago, could only dream of such a Christmas. ''I wasn't allowed to go out at all,'' she confided. ''I had to prepare dinner, so I spent a little time praying while I was cooking, and I hummed myself some Christmas songs. ''I didn't mind Christmas Day so much, but I would really like to have gone to Midnight Mass, because I've never missed it in my life before. ''They didn't give me a present, or say Happy Christmas - I suppose I wasn't expecting it.'' Daisy, who works in a Happy Valley flat with four single expats and two cats, was given enough for a return ticket to Brunei to see family members who live there; Emily received an extra month's salary, and Mexima was very happy with her $1,000 and a boxof chocolates. Mary Luz and Lina were given a coat and a leather handbag - and two days off. Jane and Florence had nothing - although they were expecting that Lunar New Year would be a better time for gifts. All four of them, together with other members of their charismatic revivalist church, had spent Saturday in Victoria Park ''playing parlour games, praying and singing''. ''It was a very joyful day. I suppose what would have made it really good would have been to have stayed overnight with my relatives and friends from the church. But my employers forbade it; I think they thought I would go to a disco or something,'' Janesaid.
