A lesbian woman received an unexpected, heartwarming letter from her close-minded grandparents after coming out to them and revealing her engagement to her girlfriend.

California resident Katie Mathewson hid her orientation from her grandparents because of their conservative views but realized after getting engaged to her girlfriend that she felt compelled to reveal the news to them. The letter she received from them after doing so surprisingly runs contrary to their conservative beliefs:

Dear Katie!

Thank you for sharing your happy news with us Katie. The most important matters is your happiness with MacKenzie for the rest of your life.

The rest of the world will follow the ideas as the time moves on, and that is their problems! Just be understanding for those who don't. I have been looking for an engagement card just right for you but not successful.

Sorry – Your grandfather and I are getting older everyday – moods change as the aches and pains occur and yet some days we feel energetic and ready to do anything so we will see by that time, August 28, 2016 it's still long time yet.

We send our congratulations and blessings for you health and happiness and most of all no matter what may come – we still love you very much!

Mathewson posted the touching letter to Imgur while describing that her Korean grandmother wrote it in English although it's not her first language. You can read the physical copy of Mathewson's touching letter below:
