They will never understand.
We had visiters from Nigeria stay at my school during summer break. Not immigrants, just visitors here to see how we do the whole trade-school thing.
First they asked if they couldn't come back when it was warmer, at the warmest time of the year.
Then the school management sendt out e-mails to all staff and enrolled students to lend them cardigans, sweaters, scarfs and other winter clothes.
Makes it hard to understand that so many of them dream of migrating here, when they absolutely can't stand outdoors temperatures at any time of the year.
