There are chances that at some point during your Erasmus exchange you will have some argument with your flatmates. Why? Most recurring reasons have to do with cleanliness, noise, privacy but it could even be about the money you share to buy toilet paper... Yeah, sharing living spaces such as kitchen and bathroom can be super fun, but the truth is it requires a lot of patience, a lot of honest talks and loosing the pride of always wanting to be right. I've shared houses for so long I can assure you that even when you think you're the most attentive, the most clean, the most respectful person, well, there'll always be someone else thinking you're awful. Because in the eyes of that person you're just annoying, picky, always complaining and in the eyes of someone else you'll even be dirty, too noisy, always around... Not only everyone is different, but living habits are something we don't want to give up as we feel like the household we grew up in is being judged. When a flatmate tells you "not cleaning with disinfectant is disgusting" it sounds like your family is being referred to as disgusting. That hurts. Arguing with flatmates over such issues not only hurts and can lead to bad living experiences, but is really not worth it. Remember that when you're a grown up you need to make compromises so everyone can be peaceful. The key to not take things personally, to also not offend someone else when it's you thinking "my flatmates are disgusting", is to have clear conversations about your habits, your budget for shared stuff, your personal circumstances, your cleaning standards. Just talk things through and find compromises so that everyone put some efforts to make things work and understand everyone's perspectives. Because if you don't have such a conversation from the beginning, you'll only encounter more difficulties: if it bothers you that nobody else brings the trash out, say it, perhaps think of schedules if you notice nobody else puts efforts or instead someone will deal with a task you don't like to do so much. Whatever works for you, as long as you are honest about things that bother you and do your best to make it work when you're bothering others. "Patti chiari amicizia lunga" we say in Italian.
