Murienn, I am only old fashioned when it comes to technology and things like sending thank you notes, in writing! Years ago, my kids even beat me down to allow them to wear jeans to religious school and not get dressed up. Still get nervous wearing pants in the sanctuary of the synagogue, though.
Other stuff, not so much. In fact, my nick name was Tilly toilet mouth in high school, and that was given by a teacher... really, I spent half of my teenage years hanging out on the Boston Common and I don't remember any of it .
This has nothing to do with bikes. I hope the OP likes her bike!
