Your mistakes are your friends

Yesterday in a completely crammed tram I witnessed an impressive interpretation of this phrase.

Next to me a woman was sitting, listening to some music (not exactly my style, but never mind ;). Opposite was another woman, which suddenly turned towards my neighbour, asking: "Sorry for disturbing, but where did you get this nice player? It's so cool and small, just to clip it to the jacket!" - The other one was a bit startled but told her this was the ipod shuffle and the shop where she got it from.

The woman took out some really colourful book and a calligraphy pen (with violet ink!), wrote down "ipod schaffel, saturn", looked a bit doubtful and showed it to the other one - "Like this?" When the other woman corrected her, I expected her to cross out her 'silly' writing, as i would have done. But instead she smiled to herself, chuckled, and drew a heart shape around it!

Sounds very trivial, but the moment was so impressive that the woman next to me and myself exchanged surprised glances. It's just not so common to deal with these kind of mistakes in that way, even though some wise people keep advising it very convincingly.
