I can teach and share with you the Malay, English and maybe even Portuguese if you are interested. As for learning, I wouldn't mind to improve my Japanese as well. As for sharing, maybe I can share some of the knowledges that I've learn over the course of my travels

I think some of the things that I can offer the hosts are my time, company and companionship. For example, if you need someone to spend time or have dinner with, I can go with you. If you need some listening ears or if you want someone whom you can talk and share your day with, I'm there for you. Also, I can offer a lot of other stuff such as cleaning your house for you etc but its not just coming to me right now
