Well im sure you have seen the site with all the different ways to tell if you're an Irish Dancer..But thought lets make our own here on Diddlyi... so lets see how many diffrent things we can come up with! :) :)
...if upon hearing any piece of music in 4/4 time [no matter what - rock, metal, disco...] you start beating out/jumping out your new reel step :) or composing your own Irish choreo!
...you can't stop moving your legs under the table during boring school lessons or working conferences.
(and I totally agree with the sock glue/accordion music and every other 4/4 music, I really like those :-) )
people at your work/school begin to comment oddly on your most comfortable standing position (your arms glued to your sides, your sholders back, and your feet turn out) and you didn't even notice you were doing it!
(ive gotten a few "why are you standing like that?" before)
....when you don't remember how to skip 'normal'
....when you find yourself walking the stairs tiptoed and arms glued to your sides.
....when you start doing random moves with your feet, when waiting for the bus/train/metro (an exellent way to stay warm BTW)
