Parents.

I have been travelling for 12 years and I really want to spend time with them now. Both are above 60 and this is the ideal time to be with them.

You might ask why they don't just move. That's because the bulk of their life is spent here. There social circle is all based here. It keeps them busy at this age. They visit my siblings in US every year but after a few weeks they get bored. We don't push them because at the end of the day we think it's criminal to move your parents to a totally new place in their age to start a new life all over again. They've worked really hard all their lives, it's time for them to enjoy.
