Material that is TSFE can be opened on any browser at anytime anywhere in any company. TSFE material is not guaranteed to delight, but no one in the room is going to fire, disown, or break-up with you because of what's on the other end of a given link.
Some examples of TSFE material include: like cats, bears, other cute animals (not in distress, or ironically grotesque violence), unicorns, clean jokes about popcorn, poetry about penguins, calm MIDI renditions of classical music, the sound of the ocean, colors, and happy babies.
The only disclaimer is that if you happen to be in the company of someone who for some reason hates the above things, or other things similar to the above things, then maybe...well...then maybe you need new friends. Cause, honestly? Who hates babies and unicorns?
Jerks. That's who. Maybe we just need to label all the awesome content on the web as NSFJ (Not Safe For Jerks).
Yeah, you know who you are.
