HAHAHAHA! I still get excited too!

And of course I hear my friends with natural hair saying the same things
"I think she was having an off day because this isn't my usual cut"
"Its the same colour product I always use but this time its come out a different shade"
"I've been going to the same hairdresser for years but but just lately the standards have been dropping"

Its obviously just the nature of hair and anything done by hand.
Results vary.
