Ok, this is one of those sharing moments, right? Get in touch with our inner-selves, our feelings, et all? Forget it, I'll just tell you how my callsign was created...
Once, someone told me that I was like a sparrow, allways jumpy and erratic, flying around and without a purpose...It stuck.
In Warbirds, my first online experience, our callsigns could only have six caracters long, so, I took the scissors and chopped one "r" off the spar(r)ow...
Sparow since then.
Cheers,
