It drives me insane when someone in a social setting or professional setting answers their cell phone and starts talking loudly over the group that they are in. I mean seriously go some where in private and talk if you have to answer your phone. I don't want to hear your entire stupid conversation about what your husband should pick up from the grocery store. I feel like it is very rude to do that. Like it literally makes my blood boil. Am I overreacting? And yes this scenario just happened to me.
