superhuman strength

Guess what happened to me yesterday???? as i was on my way home... i decided to take off my spectacles and give them a wipe with my shirt.... when suddenly, to m y horror, i felt a crack... i lift up my specs and this is what i see..



Arrrrrrrghz!!!!! i broke my spectacle lenses just by cleaning them? did i just get superhuman strength or something?? how is it possible to break PLASTIC LENSES...

anyway, it's probably some manufacturing error or something... took it back to the shop and the shop says they'll do a complaint for me. and i should get get the lenses replaced for free. they better... those specs were only 4 mths old!!!!
