What's that?

It's great when just being yourself can make folk happy! We went around to my sister and her partner's house where they had been getting ready for a surprise birthday party which in the end didn't happen as the Guest of Honour and her three children had all come down with a lurgy. The decorations were up when we arrived and while most of the balloons and other bits and bobs had been relocated to the Birthday Girl's house, the Happy Birthday sign Wa and Ma had strung together was still there. It wasn't until we were in the middle of dinner that I noticed that Birthday had a couple of letters in the wrong order. When I mentioned this, Wa and Ma burst out laughing and high-fived each other. They had done it intentionally and had been sure that if anyone noticed it would be me - they were so happy they'd been right.  I'm so glad my reputation for noticing stuff remains intact - and that they enjoyed it so much!  I'm just stunned that it took me over an hour to notice!
