Coffee or Cough-ey?

Last night we were reading a story to Sean before bed about colors. One of the pages showed a cup of coffee and Sean pointed and said, "hot". Dan told him, "that is coffee". Sean gave him a look and then said, "me, coffee". Dan said, "no, that is what grown ups drink, like your poppy". Sean said over and over again, "me, coffee, me coffee," and Dan responded with, "oh, you drink coffee eh?" Sean said, "yes, me coffee," and then proceeded to do a fake cough a few times and then laugh. Dan and I just burst out laughing. I guess Sean meant, "me, cough-ey". ha ha ha
