What to do with this girl!!

OK. Look at this girl. Isn't she sweet and innocent?

Now look at this girl. Sticking her hip out. Trying to act cool.

David and I have major worries with her.

There is a boy in her primary class who lives next door to us. A couple of weeks ago I was in primary and noticed they were sitting on the same chair. OK I thought, as long as they are quite. Then he would put his arm around her shoulder and later she would put her arm around his shoulder. Then they would hold hands. Later I saw Eilish scratching his head (I am sure he loved that). This went on the whole 45 minutes of sharing time. I even had other leaders comment on what they were doing.
Then last Sunday...again I was in primary. All the Jr. primary came in and sat down. Then the music stops and the person who is conducting gets up and starts the meeting. I then looked around and noticed Eilish and this boy (who is younger, my daughter is the "older" woman) not in primary. I go looking around the building and as I was coming back to the primary room because I couldn't find them, they come walking down the hall holding hands. I asked Eilish where they were and she said they were just walking!!! Already she is skipping class and walking the hallways. For those who may not know this...she is only 5!! 5 years old and already acting as if she is a teenager. I told David it is time to get the shotgun out and put it by the front door. :>) Does some one have a good and strong lock, without the key?
