I think Mexico are really being a bit of a stick in the mud here being disagreeable to a fair proposition which will be conducive to trade between both countries.
Only yesterday, I informed my next door neighbour John, that I was going to build a new fence panel with concrete posts and because my house is bigger than his he should pay for it.
Whilst my garden is clean and tidy looks great, he gets to benefit from all the lovely flowers and vegetation.
His garden is rather messy and Mrs doesn't like seeing their clothes on the washing line.
Unlike Mexico my dear next door neighbour John, said sure thing no problem, just send me the invoice when you're done and he'll pay for the new fencing.
Now there is one very reasonable good man. If only all neighbours could be so honourable upright citizens the world would be so much better.
