This is time of year when we think about giving and receiving presents. Can you find a little
extra(额外的东西)to give? On this page we suggest a few organizations you might like to help.
Littleton Children's Home
We don't want your money, but children's toys, books and clothes in good condition would be very
welcome.
Also,we are looking for friendly families who would take our children into their homes for a few hours
or days and give them not only food but also love. You have so much-will you share it?
Phone Sister Thomas on 55671.
Children's Hospice
We look after a small number of very sick children. This important work needs skill and love. We
cannot continue without gifts of money to pay for more nursing staff(员工). We also need story books and toys suitable for quiet games.
Street Food
In the winter weather, it's no fun being homeless. It's even worse if you're hungry.
We give hot food to at least fifty people every night. It's hard work, but necessary. Can you come and help? If not, can you find a little money? We use a very old kitchen, and we urgently need some new
sauce pans. Money for new would be most welcome indeed.
Contact Street Food, c/o Mary's House, Elming Way, Littleton. Phone 27713.
Littleton Youth Club
Have you got an unwanted chair? -a record player? -a pot of paint?
Because we can use them!
We want to get to work on our meeting room!
Please phone 66231 and we'll be happy to collect anything you can give us.
Thank you!
Night Shelter
We offer a warm bed for the night to anyone who has nowhere to go. We rent the former Commercial Hotel on Green Street. Although it is not expensive, we never seem to have quite enough money. Can you
let us have a few pounds? Any amount, however small, will be such a help.
Send it to us at 15, Green St, Littleton. Please make a check payable to Night Shelter. You can also
call us at 62735.
