It's a fantasy role-playing game.

DM: You are Mollymauk Tealeaf, a tiefling blood hunter . You are the member of the famous group of adventurers. Previously,  You had discussed with them, last time, a plot - fixing their seemingly not-very-well-put-together plot into a better direction (thankfully) - to acquire a wax seal within the home of Lord Sutan, to create a letter that you feel would be incriminating. Then to infiltrate the High Richter's home, do the same, and then report them to the Lawmaster or whoever else you think would be of higher estate...
DM: Ten. Nothing easily does so. You can try and pry one of the panes out, but there’s a decent chance it might break in the process if you’re not careful.
Player: That’s fine.
DM: You’re going to try? You take one of your blades and you wedge it up underneath where the metal bar is, it’s holding the pane in place to see if you can wedge it out. Go ahead and make a straight dexterity check.
Player: Nope. One.
DM: It shatters and breaks on both sides of the window. You watch as the window shatters outward--
Player: I’m going to jump out of it.
DM: The pane itself is about that big, so you’re going to take more of the window with you to do it.
Player: Yeah, that’s okay.
DM: All right! You shoulder-roll-leap through, shattering the window out of the infirmary, rolling into the alley. You see this happen as Molly is a chaotic spill of glass shards and purple skin.
