Thinkbot says always heed the warning triangle.  It's trying to tell you something even if you're not interested.  One may save your life one day! (Well, not the triangle itself of course, that'll just stay stuck on the wall or a pole or whatever.  I meant one might stop you doing something or going somewhere that'll cause your socks to pop.)  (Unless, on the other hand, you're not wearing socks, in which case you may be 100% invulnerable.  I'm not sure, I'll have to check and get back to you.)
