Sadly, my son hasn't played with Thomas in about 7 years, but we were definitely experts back in the day. I remember clearly Mr Conductor telling us that Toby "didn't know that James is boastful, and doesn't always tell the truth"...but that certainly doesn't make him mean! James was one of our favourites.
Now, those Troublesome Trucks, on the other hand...
Seriously, we still quote the Thomas videos around here. For example, rather than tell our 13 yr old son that he smells bad and needs a shower, we might say "All trains must wash down daily!"
If we are trying to manouever something in a tight space, we might quote Duncan and say "Tunnels shoud be tunnels, and not rabbit holes!"
We really watched waaaayyyy too much Thomas!
