My cousin and sister (sis is MOH, cousin is a BM) are throwing me a bridal shower. My FMIL is throwing me another one. The cousin/sister shower will be at my parents' house, and the FMIL one at my house. Should I get them gifts to thank them for hosting? Someone told me I shouldn't worry about gifts since the showers aren't actually being thrown in the hostesses' homes...is this true?
