Zak and Alfie had some friends over to play today. They were all hapily playing upstairs and we were chatting downstairs. All of a sudden Zak came running into the front room hysterical and covered in yellow powder! He was crying that his nose and eyes were stinging. I had no idea what was going on. It all became clear when a very upset and apologetic Alfie came in brandishing a tin of mustard powder. Alfie had crept downstairs found the mustard powder and taken it back upstairs, don't ask why, he then shook it and gave it to Zak. Zak had then pulled the lid off and it exploded in his face and all over the landing! Not sure my friend and her kids will be returning to play any time soon!
