(One could argue that it found her one wing a tad heavy and had to get used to/adjusted to the weight difference before she could find "her wings"...
or maybe she was trying to get her bearings... Whatever reason, it seemed like she was reluctant to leave us, lingering on and saying "thank you" and "good bye" -- My kids were enchanted. 
A few minutes after we saw her reach a height even with the roof of our house and fly off towards the woods (DIRECTLY SOUTH, if anyone's interested), we saw another Monarch butterfly float in over the fence -- sipping nectar in our Meadow Garden -- and it was tagged! She stayed around, stopping at flowers as well as the hummingbird feeder. Most likely the 2nd one that was released before, but again, my kids loved it that she was enjoying our garden.
