Dear Teachers,
1. When you have difficult matters / problems / issues, you have to face them and solve them.
- Is this natural?
2. I'm very much obliged to you.
- This means "Thank you very much indeed", right?
3. - Thanks for caring about me.
- Thanks for your attention.
- Are these natural and the same meaning?
4. I'm so sorry for keeoing you waiting so long.
- Is this natural?
5. Could you do me a favor?
- This means "Could you help me?", right?
Thanks very much to Teachers,
Stevenukd.
