English in Different Ways

In my familyI speak many two different languages. I speak English and Spanish at home. I speak both, many times, because it feels comfortable at home. Many times with my family or friends we make up words that are not English or Spanish. They are words made up and used in our conversation to give a different meaning of I just use them because it makes me feel as if have a bond with that person i am speaking with.
As a child I remember speaking both Spanish and English. My older brother would tell me not to speak in that manner because I was not speaking either language correctly. Many times it confused me because I would be thinking I was speaking english when I was speaking Spanish. I would mix both at the same time. I would say workds like el parking instead of saying the parking lot. i would think it was the correct way of speaking. In class assignments , I would write in engllish and be thinking in Spanish.
when I am with my friends , i speak with them in English, but very frequently we speak with different words we makeup. Words like oh-sha which we refer to as the expression aww man. We also use words like guey which to me means loser. When we use this way of speaking it makes me feel comfortable. I speak this way only with people that i have confidence with and share with me daily.
