Only 3? Easy.
1.) Seeing my girl laugh so hard she has tears coming out of her eyes while she clutches her stomach.
2.) Hearing my soon to be 2 year old nephew yell, "Yayyyyyyy!" whenever he hears a song, and it finishes. And it can be ANY song!
3.) Looking my girl deep in the eyes and hearing her whisper, "I love you" to me.
I could go on and on and on..........
