I don't think it's about making a mistake. We all do that from time to time. I think it has more to do with you irrationally arguing like a 6 year old who's not getting her way...I would suggest next time someone points out something like that, instead of sticking your fingers in your ears and saying nah nah nah boo boo I can't hear you...take some time to consider that you may actually be wrong...
Also...the breeder who sold you your Banana screwed you over hard core...you may want to rectify that...
