[Teasing,] And what about "me and my glyphs"? Ought I to say "you and your swordplay" in the same tone, ser? [He would, of course; he admires Simon's martial prowess very much. It's an admiration (he tells himself) he's got for all templars. Maybe it's a little stronger and more personal with Simon because they're friends and sparring partners, but only a little.]

They can indeed. If it's a small enough box it's not so difficult to use a very small glyph to keep it cold; do it right and it barely requires any attention to maintain. Though more usually you'd want to use a rune for that, so you can use your cold box over and over again without relying on a mage to keep it going.

Put it somewhere I can admire such a thoughtful gift until I've decided on eating it, probably. Though there's a lot of mischief you can get up to with a coconut.

Have you ever had one? Maybe I'll share.
