Not asserting yourself can also pose problems.
In the BS my family and I attended, everyone wore their shoes inside in house. We were never told to take our shoes off - ever. We later learned that the sister of the house had wanted us all to take our shoes off, but didn't think it was her job to make her requirement explicit. Apparently, she thought we all should have known. We learned about it indirectly through the often vicious JW grapevine. Talk about controversy and hurt feelings!
It created a big fuss for a while and those of us who had gone inside with our shoes on went around muttering to one another, "Why didn't she ask us to remove our shoes?!" Some of us went to a new BS because of the sister's apparent inability to simply be upfront about the rules of her house.
