Encounter with Mexicans

When I was shopping with Mom in Crossroads Mall we walked past some Mexicans that were on the phone. I made out one word because they were talking so fast and had a accent it was hard to understand what they were saying. Although I think they were mad by the tone of voice they were using, so I most likely don't know those words. I didn't want to just stop and listen and be weird so I kept walking. Hearing them talk just reminds me of how much Spanish I don't know even though I may think I know a lot. Guess I better keep learning to be able to speak like them.
