I've decided

I've decided not to tell any one in my personal life the names in picking. Someone especially my sister is just a buzz kill and ruins the names I like. She said if I name my child Wyatt she's going to call him Earp for the rest of his life. I got upset I don't want her to call him Earp! It sounds like derp! Am I over reacting? I think she's being an @sshole by saying stuff like that.. 😑
