Lets look at the facts!
1) This scenario has us living together in some capacity
2) You have drawn conclusions about me and my specific likes, of which have satisfied your own questions! Therefore know me, at least you feel enough to make that judgement, so that we are not perfect strangers!
3) You, conceivably worry about upsetting me, therefor you feel a connection of some kind!
Therefor, I believe, through that attempted logic that I should not be upset! You were looking out for my best interest - and yanno possibly know that I would eat said bars at least in one occasion to satisfy the requirement of politeness! and yanno, stuff can be baked again, with my help of course! Should I truly love cookie bars~
Would you like me if I ... secretly tried to perfect your favourite dish, so that some day you could have the very best of what you like the most?~
