I think it's a sixth sense

So why is it my toddler can sense when we have somewhere to be in the afternoon after his nap....therefor deciding to mess with his naptime and dilly dally for an hour and a half in bed prior to falling asleep for his hour and a half nap??? OMG...it's not often we have someplace to be after naptime, for this very reason. But today I had arranged a playdate with some friends and their kiddos post naptime, ballparking that he'd be up by 2 (he usually goes down around 12 ish). So we did lunch and our normal naptime routine and he was in bed by a few minutes after 12. The child didn't go to sleep until 1:40....after numerous requests for his fan on/off, needing me to cover him up, needing a diaper change etc. UUUGGHHH!!! I hadn't even told him we were going anywhere after naptime, as I have figured out that doing that is a death sentence to any plans that I may have made for us! Anyhow, he finally went to sleep and we were still able to make our playdate just fine. I mean afterall, it was just a playdate, very flexible....thanks goodness it wasn't a Dr.'s appt or something!!!
So is it just my child...or does anyone else's kids have this sixth sense??
Have a good Wednesday!!!
