Language Boxes in My Head

My head has three language boxes: English, French, and Chinese. During French club, my brain gets frazzled as it jumps from box to box. Sometimes I hit a wall in one of the boxes and can't get out of the Chinese box to enter into the French box or vice versa. Sometimes I think I am in the French box believing that the words coming out of my mouth are French when in reality they are Chinese. Ta and toi which one is which? Being in a tri-lingual atmosphere hurts my head as I stutter along jumping from box to box and sometimes getting stuck in one box when I want to be in another.
