The misspelling doesn't necessarily mean anything. My dad is extremely intelligent, but he always complains that he has fat fingers and therefore can't type well, so he makes typos all the time, haha. Not saying that this is definitely a real parent, but it is possible!
It's not because of the misspelling. It's more to do with the diction + one post and no follow up.
