PORTLAND, Ore. (KOIN) — A wedding invitation sent to the wrong address ended up being just what an Oregon couple needed.

Bride-to-be Cassie Warren meant to send the invitation to her aunt and uncle in Eugene — about a 20 minute drive from where they live — but being in the midst of planning a wedding, she wrote down the wrong address.

However, sending the invitation to the wrong address ended in a sweet message for Cassie and her fiance Jesse Jones — who are getting married in June. 

Cassie told KOIN 6 News that they received the returned invitation in the mail last week on Monday. There was a message and $20 inside.

“I was at first annoyed that Jesse was so worried about opening mail and not focused on the conversation we were in the middle of, but after he opened it and saw the note, I was just grateful and felt so blessed,” Cassie said.

The stranger wrote on the front of the invitation, “I wish I knew you — this is going to be a blast. Congratulations — go have dinner on me. I’ve been married for 40 years. It gets better with age”

Cassie and Jesse, who are fans of Harry Potter and Star Wars, said the person also wrote “Live long and prosper” in the corner of the envelope — a nod to the popular Star Trek series. Their wedding announcement shows Jesse in a Star Wars shirt holding a light saber and Cassie wearing a Harry Potter shirt holding a wand.

“I don’t know if she knew or just assumed because of wedding announcement,” Cassie said.

The couple put the money to good use. They went out to dinner at a Japanese fusion restuarant with a close friend who won’t be able to make it to their wedding. They said he’ll be deployed beforehand.

Cassie and Jesse met 2 years ago online, though Jessie likes to make up other scenarios for how they met when people ask them — his favorite is the classic diner guest and waitress scene. Cassie will usually stop him before he talks too long about each fake scenario, though.

Jessie proposed on the 4th of July. Jesse is a personal support worker for a family who has kids with autism. Cassie is a nanny for a family in Eugene.

While they still don’t know who wrote the message, Cassie sent another letter to the same address — this time on purpose — to thank the stranger.

“It was just a thank you card,” Cassie said. “I thought she should know her act of kindness was appreciated. Not many people would do that for a stranger.”
