I love my gf's melodious chirpy giggles. Sounds almost child-like, and I can't get enough of listening to it.
I set her up once; had her on my cell phone and I cracked a joke and recorded her laughter lol (told her afterwards of course, didn't want her to feel shy and not laugh). Now I can just listen to it whenever I feel like it; brings a smile to my face 🙂
