At some point Lucy's problems with outfielding become more the result of her fussiness and ill-temper than more personable factors. At least her absence from play doesn't see to have caused Charlie Brown's team any problems this time.
The beginning of a long-standing Peanuts theme, Lucy as problematic baseball player. Note here her position is center field. I'm not sure, but I think most of the time she is a right fielder.
