In Korea the change of seasons occurs with the change of months. For example, summer starts on the first of June, rather than partway through the month like in the West.
So, according to Korean measurements, I've now been in Korea for three seasons. I came in February and saw the end of winter, I stayed through the entire spring, and I am witness now to the new start of summer.
This year is flying by, and I take comfort in the fact that I have no intentions of returning home when I complete my contract.
