I was not revealing my son's name to anyone yet but my sister begged me to tell her, and when I did she said 'mhmm its okay'.. Which I really didn't ask for her opinion. And today she comes up to me and says 'I think you should name him Liam.. Do you like the name Liam?' UMM no. In going to name my son whatever I want to name him. That is so annoying, honestly people should know not to do that.
