Ethan Enjoying his holidays ..and the mystery of the letters on the sofa?!

As you can see Ethan is having a ball these holidays, here he is this morning sat on my knee being silly in his pyjamas! These are his favorite pj's Grandad and Bon bought them Man utd with his name on the back.
Let me tell you we have had some spooky goings on......We were all sat on the sofa and all of a sudden there were two perfectly formed indent of the letters AN on the couch?!! weird I know, so we rubbed them of and didn't think any more of it then next day, (after me telling daddy and he thinking I was totally bonkers as oppose to slightly!) daddy witnessed another few letters ET !?? as you can imagine we were all a bit freaked! Anyhow this continued until a day or so ago when Ethan got of the couch and the imprint ETH was sat staring at us! imagine the laughter and the relief when we realized ITS THE PRINT ON THE BACK OF ETHAN'S PJ'S INDENTING ON THE SOFA!!!!! (idiots!) sure had us going for a while!!!!
