Quoted:
I was at her house the other day and she showed me some candy cane reindeer she made and she needed to make more.
But she was missing those craft googly eyes and I pointed that out. She got very animated and said " I knowwwww!! I need to get some!" So a few days later I told her I got her a surprise and waited for her to get off work. She asks is it was something dumb. "Oh yes very dumb" and I handed here one by one a caouple packs of googly eyes, red colored pom poms (For little rudolphs) some black pompoms, glue to glue it together and more pipe cleaners.
At each little pack of goodies her eyes and expression grew brighter and more joyful and surprised! She goes " I can't believe it and we just talked about this!"
Being thoughtful like that will get you alot further than anything else. You don't need to send anything to work to get her co-workers to aww. Just be nice for now and look for little things you can do to let her know you are listening to what she says. But don't go overboard. Just a little here and there.
Also, don't act like a pussywhipped little puppy.j
ETA: I read your last post and it sounds like you are both overthinking it before it has even started. STOP IT! and tell her to do the same.
ETA2: If you want to give her flowers, then do it. But don't have the florist deliver them. They don't even have to be made up by the florest. Get them, knock on her door and say here.
