Conversation is the best medicine. Perhaps I'll just chat him a quick note and say "Hey, I'm truly sorry that you're hurt about someone you know passing away. As much as I would truly love to help you, I have absolutely NO experience handling such sensitive situations like these. I'm the kind of person that when faced with these situations, I'll just try to hype up their emotions so they'd forget about it, or just change their mind onto something else. I'd probably just tell them to listen to the Mamma Mia! soundtrack, or give them some funny songs to try to laugh at. Laughter is supposed to be the best medicine, and that's something that'll get me out of the dump. Or perhaps write your feelings down on paper? It helps get them out and about, and stop holding them in. I find that it's better. Wet the paper an let it fly. That's what I did for a dead cat. I thought that the wind would take it to her, although in your world that's probably littering. Of course, I could listen, if that's what you'd like, or I could pretend nothing happend, Or I could send you a pig video that I had to watch in Animal Science. As gruesome as it was, the way they peeled the pig's skin off was somewhat (dare I say it) satisfying. If you want a funny anime (since I know you watch it) I could tell you to watch Ghost Stories, but the English dub. That's funny af. Or go outside and stare up at the moon and have a talk with her about something rather. It helps you feel more connected."
I truly do feel bad for not being able to help more. I feel like I'm chained onto something. I can't respond. But like... I'd try! YOU WANT CUTE PICS OF MY KITTENS, TA DA?! Maybe sticking your head in snow will help soothe feelings. After all, you'd be too freezing to think, and soon your tears would freeze your eyes closed. That's... An example of how I ruin these situations. GAAAAAAAHHHHH
