can someone help me with this tv/movie quote?

<p>there’s a girl that goes to a guy “thank you” and a guy goes “for what” (i think thats how it starts) and the girl says something along the lines of “for not always being there when i want you but for always being there when i need you”. my friend said it to me earlier today and it sounded familiar. im 99.9% sure that it came from either a movie or tv (pretty sure it was from the tv) but i can’t figure out from where and she forgot also. it’s been driving me crazy all day (this is my first post in the cc cafe- thats how crazy i’ve been)</p>

<p>nvm. i figured it out. it was actually from a short story a friend of ours wrote.</p>
