Is it normal to despise my sister for talking so much about their jobs?

My sisters talk about their jobs ALL THE TIME. They have different jobs, but they are both in healthcare. I'm glad that they both love their careers and are so proud of what they do. HOWEVER, it is extremely boring to listen to them go on and on about their work days. I'm also in the healthcare industry, but I rarely talk about about what I do unless asked. is it normal normal that I'm this annoyed with their stories? Or should THEY just separate their jobs from their home life? Am I overreacting? When I'm with family I like to relax, not listen to them tell "funny" stories or complain about how their day went.
