Everyone needs help. Everyone can give help. Most people want to help.
Asking for help:
- Can you help me?
- Please help me [fill in].
- I need help with [fill in].
- Help me [fill in].
Offering help:
- I can help you.
- Can I help you?
- How can I help you?
- Do you need help?
And then say:
- Thank you.
- Thanks so much.
- Thank you very much.
But-
"Thanks a lot." can go two ways. It can mean “Thank you very much” or it can mean “Wow, that really was not helpful!”
