Being neighborly is one thing, but this?

Last night I came home to see my neighbor from across the street, in my front yard, in my flowers, CHOPPING DOWN MY ROSE BUSHES!  What the H E Double L!!!

This was not provoked, infact I take after my Father and keep my front yard very pruned and always bloomed with seasonal flowers.  Just this past Sunday I planted all new flowers in my flowerbed and potted 5 pots around my front door.  After planting I picked some dead bulbs off my rose bushes and admired how gorgeous the newly sprouted blooms were.  I have had four different bushes, one white, one hot pink, one orange and one light pink.

I was SO in shock that I marched myself right past her into the house without even a glance at her.  Appalled I walked into the back yard to find Ryan and told him what she was doing.  He was dumbfounded and really didn't believe me, saying, "What??  The kids had planned to pick the roses and give them to you on Mothers Day".

So, what do I do about this trespassing nose-body of a neighbor?  It's a small cult-a-sac and I don't want to make a enemy, but come on, she so crossed the line!
