He lives in Nevada, she lives in Ireland. He's single and is going to graduate college this summer and do "remote work" in IT. He's known for a long time she can't safely fly due to a nut allergy.
SHE BETTER BE MORE WORRIED ABOUT THE NUT WHEN SHE GETS THERE - AYOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
People are allowed to bring their own food on board even if the airline itself doesn't serve nuts on flights. My friend's allergy is severe enough that if just one person brings a bag of nuts on board and starts eating them, she'll have a reaction.
But people can eat nuts everywhere in public, on the subway, in class, at work etc., does that mean she spends her life in locked up at home? And nothing that can be solved by wearing masks? I've been flying quite a bit during covid and was wearing N95 and even N99 masks once (regular ones were sold out), and while not the most comfortable experience, it's certainly possible to get through the day.
Ask him if he would like to take a trip to Ireland to celebrate his graduation. I'm sure he won't be starting work immediately, but if he already has a job it's an easy excuse for at least a 2 week vacation. You could offer to show him around where you live and all the cool spots. Introduce him to your friends and do some of the things you all usually do for fun. Then you can take a trip to the touristy spots, which is conveniently a great excuse to get a room for night in the city, ya know, to make sure you have enough time to see everything and not worry about the travel time and such. Then for the end of the trip, just spend the time relaxing, and hanging out together. Give yourselves the time to get comfortable doing the day to day routine, give him a chance to experience what regular life in Ireland might be if he were to stay a bit longer.
