In his eyes he probably didn't see himself as being a huge interloper, he saw himself as a guy down the street that just happened to be taking his kid for a walk a couple of times in front of her house and then just happened to have the kid in a swimsuit and a towel the next time he strolled by. The guy is a creep nonetheless but I'd bet that my husband's interpretation of it might be correct. He figured the kid would open the conversation up and seeing as he basically had to force the kid over to the pool, she didn't run over to it herself, it doesn't look like just a random happening like he wants her to think it was. Demonica should print out this thread and tape it to his front door!!!!
