An office can be a truly boring place because people are literally stuck in a building to do work.

Boo.

But a group of people at Suntec Tower 1, 2 and 3 found joy in communicating with one another between office buildings using Post-It notes.

Post-It messages

On Jan. 11, Twitter user @Gurlstrange started a wholesome thread.

We said "hi" on post-it. Then the office opposite reply leh! They said "hi!" back. I think this is the start of a beautiful relationship. pic.twitter.com/ydAcWrVJu7 — Chieftess🦄Weirdette (@Gurlstrange) January 11, 2019

In case you can't see the Tweet, @Gurlstrange and her colleagues formed the word "Hi" with yellow Post-Its on their window.

Shortly after, she found out that someone from the opposite building responded with a more enthusiastic "Hi!":

The Twitter user then cheekily replied with a blue tick.

Noticed by another tower

On Jan. 18, @Gurlstrange and her colleagues formed a thumbs up sign on their window:

And another office from Suntec Tower 3 noticed them and reciprocated with a heart shape.

Awwww.

Welcoming year of the pig

To welcome the Year of the Pig, @Gurlstrange and her colleagues formed this picture of a pig on Jan. 29.

And if you thought that was impressive enough, look what the people from the opposite building did:

They made a pig's head out of white and pink Post-Its, the Chinese character "Fu", which means fortune, and finished it off with a message that reads "HAPPY CNY!".

Is this what people used to do before the invention of smartphones?
