If you were to encounter a person with a different first language than you it would be much easier to communicate with them and break down their walls if you could communicate with them in their own language. They would be much more willing to have a more substantial conversation with you if you at least made an effort to communicate with them in their own way. That is an idea that I want to get across to people.
As far as working with my grandma and dad, I've become much closer with them because I've learned to communicate with them in their language. That applies more to my grandma than my dad, but it's brought me closer to them in a way I might not have been had I not decided to learn about a different culture than my own.
It's also interesting to see how cultures are different from your own. Seeing and understanding these differences can help you understand and bring down the divides between different types of people.
For now that's all I have and hopefully soon I will be able to start formulating my speech. I'm been really happy with the progress I've made, especially recently and I'm hoping it continues to go well until the end!
