I'm calling bs as well.He sat and watched for 10 minutes and did nothing but call you near the end of it?even with a crappy phone or camera youd
think someone would take a pic.What a drawing too.That makes you a reliable source.lol good one.
Have fun enjoy your "story"
tell your kid not to put too much interest in that UFO. if it showed up again, pretend not to see it..
Why you ask ? if its a real UFO phenomena (and not hoax from you or your kid) then the more you curious and want to see it, the more the manifestation
will occur and thats to the regret of your kid later.
