No, you are not being picky, you are being petty

Like I am when I am referring to the "is" that is missing in your second sentence (above)? And the correct grammar for your last sentence that should be "Wouldn't you think?" If you correct someone you have to make sure that your English is impeccable, at least most of the time. Mine is not perfect, but neither is yours by a far stretch. If it were, I would have been much more gracious in accepting your criticism as picky and constructive.
