No, seriously, that statement doesn't make sense.
"maybe a damn girl can't be bored"
Does that mean that, as a girl (of which you claim to be) you are incapable of being bored? If it as stated then you are contradicting yourself, either your established gender, or the point of this here topic.
If you stated you were, indeed, a male, then I would assume this is a logical error combined with a typo where as you meant to say that if you were with a girl you would not be bored. But such a statement is compleately random when read next to the comment about mail being boring (which actually it is quite interesting to attempt to comprehend, but that's another discussion)
