How sarcastically imply someone who is trying to teach you something that you are well aware in that case
I am going to find an up-to-date English metaphorical and sarcastic expression or proverb to indicate that someone who I am speaking to should not try to offer advice to me! Because comparing them, at that specific case, I am more experienced and aware about anything!
I have found two proverbs, but please let me know which one of them is in current use in the sense I am looking for:
1) Don't teach an old dog new tricks.
2) Don't teach your grandma how to suck eggs.
