Could you please help me to find out how the sentences below differ in meaning?
- Thank you for helping me.
- Thank you for helping me out. [It strikes me as an informal way of saying just "thank you for helping me, but I'm not sure]
- Thank you for being of help. [to me it sounds awkward, but I see people use this form]
I wonder if you also let me know about my taking on each case.
Thank you.
