After a seizure, you're slow cognitively, but you don't look outwardly different. So your boss might wander in while you're in a post-seizure fugue and give you a list of things to do. By the time he leaves, you'll not only have forgotten the tasks, but that he ever talked to you in the first place. One time, I went to a dinner party shortly after having a seizure. I don't remember a lot of it, but my boyfriend told me that I sat there for two hours and didn't say anything. At one point, I apparently started punching him. I only realized what happened when he told me that his friends thought it was a bit weird that I stared silently for several hours and then started beating him in public. Generally not the best signs of a healthy relationship.
Even couples who met at Fight Club talk to one another between fisticuffs.
