Name That Fallacy

Toby asks…..

We have used some of your logic texts but have encountered an informal argument we thought may be a fallacy not covered in the books. We name it after the kid who uses it.

A certain camper wore the same t-shirt all week. When my Dear Husband, his counselor, told him on Thursday to change shirts, his reply was, “Why? This shirt was fine on Monday — you had no complaints on Tuesday — no problems on Wednesday, and now all of a sudden you are saying something is wrong with it?”

Is this an established fallacy we just are not catching? Thanks!!

Can someone name that fallacy?

    I will try to answer this question, but I am not a “Fallacy Detective”.‎

    I think in this example the camper is doing an assumption (Lesson 13, The Fallacy ‎detective). The camper assumed that since nobody told home about his t-shirt in previous ‎days, nothing was wrong with wear it again and again.‎

    What we do not know is if his assumption is correct or not. If his t-shirt is the same but he ‎is watching it each day and it is clean and if there is not a rule in the work against ‎wearing the same clothing each day I considered he is doing a right assumption. And he ‎is in his right in asking why he must change it.‎

    Now, if he is not watching his favorite t-shirt each day, he is making an incorrect ‎assumption that the t-shirt smells the same as the first day. He will need more that logic ‎to solve this problem, maybe he needs hygiene and urbanism lessons or maybe he needs ‎visit the Dr. There is people that lose the sense of smell without notice.‎

    Bye, bye

    Sorry my english, I’m still working on it.

    I mean he needs “urbanity” lessons (not urbanism).

    In the third line, must to say: nobody told “him” (not home, sorry again)

    Bye, bye
