Miscarriage shirt

I bought this shirt back in July. This shirt was a symbol of what we lost. So I wore this two weeks ago at a lunch with my husband’s family. Found out today that my father in law thought this shirt was offensive to my sister in law that just had her baby. He thought that I wore it on purpose because we haven’t seen the baby yet. I wore this shirt because I can!!!! It’s my way of coping my loss of our baby. So he flat out asked her on the way from my house and said to her” were you offended by her shirt”? He than said this shirt could be offensive to some people. Seriously people what the hell!!!! I seriously can’t do this crap anymore with my father in law. This shirt is my shirt I can wear this shirt if I please. It is not about her one bit. Please guys I am about to cry because I take it anymore. Just can’t.😢
