Better idea for the Baby name issue. Tell your GF that you googled the name and the first hit was a super popular porn star. Then raise the point that you’d rather not have anyone (yourselves included) associating your daughter with porn.

So what should one do if saying ‘sorry’ is part of their job? I work in I.T. and have to deal with users on a daily basis (sys admin/helpdesk/facilities/everything). ‘Sorry’ is part of my daily vocab because it almost instantly defuses an upset employee.
