I try to go back about once per year. My family starts guilt-tripping me pretty hard if I'm away for much longer than that. It's nice to get back for a week or two, but the price of international flights really adds up after awhile.

Side note related to my question earlier today, I do a lot of my shopping when I'm back home.

every summer

I've been here for a year and a half, will be returning for four months starting on June 9.

I'll be going back in August for the first time in two years. It's been too long.
