I am amazed how many people don't know what lactose intolerance means. I am more amazed at the number of people who, once you explain that you are allergic to milk/cheese/dairy, still ask "So, what happens when you eat dairy?" Do you want to know? Do you really want to know? I told you I was allergic, so you know it's probably something bad. And I'm tired of coming up with euphemisms like "stomach trouble" or "digestive problems", so I'll just tell you flat out exactly what happens: EXPLOSIVE DIARRHEA. Now stop asking.
