Well...

...the sky was not orange, but the girl had a blast anyway. She quickly got the hang of "real" trick-or-treating and learned a few valuable lessons:
1) If the porch light is on...there are people there that want to give you FREE candy
2) You must knock (with ALL your three year old might) and knock and knock and then ring the bell...If the resident inside the house comes to the door then *Tada* "IT WORKED"!!! (She was SO cute...her liddle eyes lit up and she grinned her liddle smile and actually said "IT WORKED"!)
3) You must look the candy giver in the eyes and say "thank you"...otherwise Momma makes you go back UP the step and stand there until you say it.
4) You MUST NOT eat the candy...NO MATTER WHAT...Daddy however can eat all the candy he wants (cheers to being a grown-up)
5) The mermaid wig is VERY "scratchy"
6) Glitter makeup wears off...there is no need to be sad about this fact of life, you can still be a great mermaid with no glitter
7) You eventually get to eat ONE piece of candy and this makes the entire night well worth the effort
