There’s not really a way to. You just kind of learn to live without them over time.
Both of those places are wildly different so it would depend on you. France will be closer to home and while the culture will be different, I think South African culture will be a lot more different than what you’re used to. It also depends on what language you’d prefer to learn.
Personally, I think South Africa would be really interesting to live in
I’d say it just depends on you and the host family. With our first host student I emailed her almost daily, with the rest we didn’t speak to them until they arrived. With my host family I had told them a little bit about myself and they told me a little about them, but that was about it. I think if they don’t have time then you’ll get a lot of chances to talk with them once you’re there.
I’ve found people are usually pretty accepting, and usually care more about how you are than how you look.
I’m not exactly skinny by any means, but no one really mentioned or seemed to care about my weight except my host family (and that’s because they knew I was trying to lose weight and their comments were okay to say)
I don’t know any information on this (although if I had to take a guess it’s probably more for countries where that food item is a significant part of their meals, so I would imagine your allergy would be fine)
Does anyone else have more info?
