(　･ω･)☞. Giving a Helping Hand

Giving a helping hand can be rewarding for both you and the person who receives your generosity.
1. Determine if you prefer to help someone by yourself or choose a charity to help you. A charity is knowledgeable in finding the right people that need your help most of all. If you choose to help someone on your own, it may take more time or risk on your part.
2. Select a charity if you feel you need help finding someone to help. Most charities have the structure, administration and organisation to effectively find someone you can help. People working in such organisations are volun- teers who are dedicated to their mission.
3. Make a donation.
• Donate money if you don't have a great deal of time to help someone in person.
• Donate time if you feel that is how you can give the most. Some charities require only an hour a week while others could use you full time. You can help people in need not to give up hope.Giving a Helping Hand Giving a helping hand can be rewarding for both you and the person who receives your generosity.
•Donate food or used items instead of selling them on еBay. Charitable organisations accept many household items that you may not need any longer. You can give out your clothing, furniture or toys.
4. If you choose to help someone on your own, determine the true needs of the person. Some people may be offended if you offer help. Think carefully if they truly need and want your help.
5. Ask friends and family if they have any needs. You may find someone in need very close to home.
6. Don't expect anyone to appreciate your help. If you are giving for com- pliments or gratitude, you may be disappointed.
