I see what you’re saying, but if you randomly come out and say “Here, I got you an Amazon gift card out of the blue, buy whatever you want” after they did something like this they’re going to know whats up. Also, I’m pretty sure most dads would rather not have that thought in their mind when they see an Amazon box addressed to their daughter and she runs to her room to open it up. I’m 38 and my dad is your typical “Dirty Old Man” that started making sexual comments about women around me when I was like 13, but I don’t think I ever felt comfortable talking about anything like this around him until I was like 19 or 20.
