if I were your abuela...
I would disown you as "nietos"
this is NOT the way you would treat an 84 yr. old! especially taking them through ANY connection in MIA!
let's see... 1926 (84 yrs ago), Abuela was born and for most of her adult life, she probably ferried the River Plate. If only she knew that she was going to be put thru hell in 2009... Que pena!
