I live just next door from the school founded by l'Abbé de l'Epée for deafs and mutes, so, everyday, I cross flocks of youngsters, signing, going to school or coming out of it.
Most shops around it used to have some specialized gadgets and once I bought an alarm clock that was buzzing and vibrating the night table it was on... Soft noise for one who can hear but woke you definitely (that was before the cell phones era).
It broke down and the shop changed so I didn't find another one as I liked it (it was a Jaz brand).
Every day I think I should learn how to sign, just in cas one of those youngsters ask me something... And I also have student with hearing aids from time to time...

The following picture didn't make it to the photoblog on street art, but I'll stick it here to thank you for that diary, and because those kids wanted people to see it :-)
