What does this expression mean in English ? いや俺も俺だけど [Master/servant] Context: MC is talking with his servant about the fact that when he was still a student like her, he also forgot everything the moment after the test was over. > G1: > > MC: …… > > G1: > > MC: **** Can someone help me understand what he meant here?

Forgetting what you have learned is a bad thing.

So the scene is that G1 is happy to know that MC did the same (bad) thing when he was a student. MC tells G1 that it is not something she(?) should be happy about, and means something like "well, I did wrong, too".

The intention of the whole phrase is "The fact I did the same thing should not be the reason you are happy about, (because the forgetting is a bad thing), but then the blame applies to me, too (because I did the bad thing)."
