Hebrew is the official language of Israel, but many Israelis also speak English. There is also a large population of Arabic and Russian speakers there.
They use the Israeli new shekel. One U.S. dollar is equal to 3.62 Israeli new shekels.
It is cheaper to buy in bulk, so I bought a six pack of 1.5-liter water bottles that lasted me the week. The six pack cost me about 11 shekels, which is about $3 USD.
The food in Israel is so delicious that it is impossible for me to choose just one! My three favorites were falafel, hummus and shawarma.
For my next job, I am moving to Peru so I have been listening to news podcasts in Spanish rather than music because it's the only time that I have to practice my Spanish right now.
Honestly, the most fun activity was getting to see my friends. During my time in the Peace Corps in Madagascar, I made many great lifelong friends. My best friend is currently living in Israel along with another one of my friends, and a third friend was able to make the journey out to Israel from Wisconsin! So we had a miniature reunion.
