Bathing the Plates

Another translation (or not so translated) story......
Last night, I told Jacque to go and pick up some toys out of the sitting room floor. I said it correctly! Then she asked me what I was going to do while she was picking up toys (meaning I should come and help her).
I was on my way to wash the mountain of plates in the kitchen sink. But, the only problem was I couldn't remember how to say wash the plates. So, I just told her I'm going to bathe the plates. She just shook her head and laughed at me. Then, once again, politely corrected me and told me she doesn't know English that well. I think that was to make me feel better for speaking such atrocious Luganda.
