Can someone interpret this, please?

Ok, so I've been chatting with an old school chum on Facebook....maybe once a week we'd pass an email back to each other. Then out of the blue he asked me to dinner, I didn't expect it, but I said yes. He had already sent his phone number a few emails back, so I retrieved it and called him to set the date. We arranged the date and area, he told me to pick the place. Two days later I called him back with my suggestions, and he was ok with it, and he asked me to email him the directions which I did. We set a meeting time, chatted for about 20 minutes on the phone, and he said he'd call me before then anyway. Two days after that conversation...he EMAILS me to CANCEL the date. Doesn't call, emails. He wrote that he has his nephew's bday party that day. Now, to me, that sounds like BS. If he really did have his nephew's bday party, wouldn't he have CALLED to cancel? I would think that it's easier to lie in an email than on the phone....comments, please. BTW, I am disappointed that he cancelled, I was looking forward to our date!
