One of Luke's favorite things to do is get into mischief.  No other way to describe it.  He absolutely loves doing things that he knows he's not supposed to do.  And he always makes sure that we're watching when he does them.  He'll actually pause and wait for us to stop what we're doing and look at him before he does it.  And then he laughs hysterically.  We've got our hands full with this boy!

Here are some of Luke's guilty faces:

 The "you caught me" face.

 The "I'm about to do something I'm not supposed to do but I'm waiting to see if you'll come stop me" face.

The "are you watching me cause I'm really about to cause some mischief" face.
