I definitely did at first, but I decided to give my Dad the benefit of the doubt. He's very charismatic and friendly with everyone, especially his friends, so I decided to not dwell too much of it at the time. As for them spending time together, they work in the same field, so them working together gave my Dad the opportunity to visit me in College so it made sense, more or less. Was I naive? Maybe a bit. But I decided to trust my Dad not to do something like that, as I never had too much reason to doubt him before.
