If you need a little something to get you through Monday morning, this one's for you.
A woman has shared the incredible response she received from a stranger after accidentally sending her a graduation invite.
Posting in Reddit forum 'Humans Being Bros', the new graduate explained she sent an invite to her extended family's old address and received a "touching letter (and $20!) in return!"
The stranger's letter reads: "Regretfully I must inform you that [her relatives] are not located at this address. I bought this house in September and am not acquainted with the prior owners.
"I unknowingly opened the envelope addressed to them by mistake and am returning the contents to you.
"That being said, I offer my congratulations! My niece attends [blanked] college of engineering.
"Though I don't know you, I am proud of you for pursuing a career in a STEM field."
STEM stands for science, technology, engineering and mathematics, fields which are typically dominated by men.
"Us women have a lot of work to do to take our place in science and I am happy you are joining our ranks," the letter writer went on, adding they were a 35-year-old mother of two, and "didn't want to pass up the opportunity" to wish the new graduate well.
"You are going to do great!" she ended the card.
The post racked up over 400 comments from Reddit users who were blown away by the act of kindness.
"The fact she saw this as an opportunity to send you money means she is going to be a terrific grandma one day," one person wrote.
"This is so beautiful and wonderful and such a true representation of how loving and kind we can be to one another. Great post. Thank you so much for sharing," another wrote.
"This really brought me up at the end of a hard day. Thanks for sharing," added another.
