CapriUni, MidiText is fine. E-mailed MIDIs is fine.
I've grown up just enough that I pay my bills, sometimes on time, and I show up where I'm supposed to be. Other than that, my grown-upness is mostly a disguise I wear to hang around with other grown-ups, who are just as likely to be wearing grown-up disguises. (I wrote a song about this too. What a surprise.)
