doggies and learnings

as a kid, i was taught that dogs produce the sound "baw-aw-aw!"
at a later stage, i learned that this sound is called barking.
now, i'm 28 years old (some say i'm at my prime).
today, i learned - and actually heard - that people could bark too!
aah, life! you'll never stop learning.
what will i learn tomorrow? that people bite too? hmmm... that would be a sight.
will let you know.
