I wanted to know the same thing, My son is 6 and has a weird imagination, he generally says what he thinks you want to hear. It's frustrating and scary thinking they may interview him, because what he says doesn't mean its accurate. I once asked him why he loves it here and he said "I love it at his house because he has an xbox." He doesn't realize this is OUR house, not only my husbands house because we've only lived here 10 months and his father lives elsewhere. Since my husband had this house already when we came here, which is why we came, to see the new house, and then we were going home to file for a fiance visa, but ended up staying, so my son has always called it "his house"
