Dealbreaker

Don't think it's a dealbreaker as such, but new flatmate is picky with food. This I do not like. He doesn't eat fish. Or mushrooms. Am sure there are more things. What worries me is that people who are difficult with food, can also be difficult with other things. Allergies are one thing, but not liking food is like not liking life. Am I wrong? There are very few things I do not eat (i.e. when I allow myself to eat at all :)...diet is on hold a bit but not forgotten). I'm not keen on...and here I was gonna write something but cannot think of anything I do not eat. Of course there are things I like less but I eat everything that is served. Ok I know, once I was sick and my ex did flour soup (mehlsuppe) that was supposedly good for you. That was really disgusting. The smell and the taste, yuk! Ok, so not a dealbreaker. Fortunately flour soup is seldom on the menu :)
