I've met picky eaters - they're usually small children who are afraid to try/eat something with what could be considered a "weird" texture. This sometimes follows those picky children to adulthood- which can inadvertently become annoying for those of us that get into relationships with them. I am not saying that they are exactly annoying. I am sure most of us (myself included) find ways to make due with what their partner is interested in eating, but on rare occasions I know it can be frustrating.
Signs you're picky eater:
1. No Seeds (in anything)
2. Nothing Green
3. All Fruit is gross... except sugary fruit (basically pineapple)
4. Bacon is your friend
5. Pizza is a yes
6. Only boneless chicken
7. Italian food isn't great (unless it's mac and cheese)
8. Mexican food is a no
9. Unless it's a quesadilla (basically just cheese and chicken... or just cheese)
10. Chinese/Thai/Japanese/Indian food is a - Never Going To Happen
11. Rice is weird
12. Applesauce is great
13. Chicken Nuggets are Bae (Strips are good too)
14. Pizza Rolls = yes
15. Pizza-like things are also a yes
16. Ramen is OK
17. Eggs are gross
18. Bacon is Perfect (again)
19. Seafood will Never happen
20. Condiments are basically a No.
21. Cheese in EVERY form is Perfection
22. Bread is given from the GAWDS
I do not claim to have all of these correct. Every picky eater comes with their own food guide - but some of these, I am sure, are relevant. It's okay if they won't eat sushi with you, just make sure there's a chicken option (or if they are a vegetarian or vegan) in order to make eating with someone alright. It takes a little compromise to work it out. It's okay if they don't like ranch... even if you're not so secretly judging them. hah.
