That's rude. I think, my English is just fine. Can you spot the wrongs I've done in my sentences?

Yes. I can spot them.

Then please help me by doing so. I'd love to correct myself.

I can't teach you english. Only you can do that. Try reading some english books

I did not ask for you to teach me English. I told you to spot the mistakes. If you can't spot those then leave. I know people like you. Just another uncivilized person on internet.
