Hello there,
My name is Dave and I am writing to you from Toronto, Canada (my hometown). Usually I live in Nagano, Japan, but had to return here a few weeks ago. Sometimes I teach English in Japan so if I can offer you any help, I would happy to do so. I am much older than you so I hope I don't scare you away, but I enjoy doing language exchange when I can.
I like your profile and picture, nice and easy.
Anyway, just a short note to say hello and thank you for reading this. I hope to hear from you,
Until then,
Please take care and have a nice day,
Sincerely,
