Can I speak to Grant?

For the past two nights our phone rings what seems like every 5 mins and this sweet little girl says, "Can I speak to Grant?" The KDG's must be exchanging phone numbers at school. Yesterday Grant came home with Joey's. Within 10 mins he had called Joey twice and Joey called him twice. And of course that little girl (Logan) called. It is sweet until the phone rings at 9:15 and I leap out of bed to answer and it's Logan and she hangs up on me!!!
