I came to BA a few years ago for fertility treatment after other countries have failed. I had a daughter there who turns 2 this week and after getting pregnant a second time, we went back to the states to be around family, what Pericles said the "inefficiency and lack of long term planning", and for me, the lack of variety in food.
Well, the grass is NOT greener here and I'm in Hawaii. Family gets to you after a while, inefficiency exists everywhere (just in different measures), and after having a family, it's so much easier to cook and prepare meals at home. I'm still looking for restaurants here that watch your toddler while you eat.
In addition, we've made wonderful Argentine friends and have been a apart of many family functions.
So, there's our vote, we consider Argentina our home. And we're working our way back...
