Certain types of allergies can be dangerous. Anyone who's been on a plane lately will know about the 'severe peanut allergy' announcement, where they stop giving out nuts and ask everyone on board to refrain from eating their own nuts (LOL).
I 27(m) am allergic to seafood, unfortunately my 25(f) gf adores it. Ever since we got together, abt 3 years ago, she's made an effort to eat it as little as possible, which I appreciate, however I wish she'd completely stop tbh.
The other day she went out with her friends at a restaurant. When she got back home I tried to kiss her but she stopped me and told me she just ate seafood. I got a bit disappointed because I was looking forward to spending some time together with her and I told her as much. Then I said that maybe it would be better if she'd just give up on seafood all together.
