<p>Update: just spoke to son - he says he told girlfriend he asked if she could come with us, and it turns out he hadn’t even asked her about it! She wants to just drive herself to make sure she’s back with enough time for a good night’s sleep Sunday night before work Monday, and doesn’t want to make us leave earlier than we want to. I thank you all again for your advice, and I will definitely take the time to get to know her better.</p>
