They're the one person who I never tire of hearing from.
Organize my work, social life, etc around them.
Or just cast the above aside, if I can't make time.
Feel desperate and needy, even though I've only sent one text message.
They randomly pop up in my thoughts during work, or whenever.
A joke that they told a month ago still makes me break out into a stupid grin.
The thought of them makes my toes curl; the sight of them nearly buckles my knees.
