Chagigah 18b. “Whoever washes their hands for fruit (even though they’re only obligated by bread) is from the haughty of spirit” Mishna Berurah 158:22 states that this is because he makes the statement about himself that he is careful with mitzvos even beyond the letter of the law. I don’t understand, isn’t that a good thing? Although I can’t quote off the top of my head aren’t there plenty of times where that is seen as a good thing.( I.E Women being stricter than letter of law by Niddah)??
