You need to step in her shoes for a moment. You may have had good intentions, but you effectively silently handed her back a gift she gave you, a gift of her innermost feelings.
Look at it this way. She is grieving and wrote a poem. She feels a need to share her feelings with someone but is hesitant to show a poem she wrote, afraid it would be considered trite or dumb or badly written or self aggrandizing. She thought, I can show it to X. She’ll understand. So she texts you the poem and a picture of her friend and herself. Probably hoping you will read it with a gentle spirit and text her back in a few minutes with what you thought about it ‘oh Jane, what lovely words you wrote for Mary, your love for her is evident, she was like a sister to you’ obviously do better than that, I’m just giving an example.
Instead, you received her text, printed out the poem and framed it and the photo and sent it right back without saying anything much…for what purpose, for her to place on her own mantel? It is more likely something she was thinking of sending to her deceased friend’s parents or siblings but didn’t know if the poem was good enough or would be considered ‘twee’.
Anyway, you sent it back as if, why is she sending me this, it is only really meaningful to her, is she saying look at this great poem I’ve written, so I’ll frame it and give it back and she can display it in her house since she’s so proud of it.
As I said before, this is not what I think, but she might be self conscious already and you doing that makes her feel she was pretentious in sharing it with you so you had a little laugh in framing her fancy writing and saying here you go. Put it on your table in the foyer, dear, so it’s the first thing people will see.
It’s just weird what you did. I know you don’t realize that, but it is weird.
