In my senior year of college, I broke up with my then-boyfriend late at night. My dear friend Kate called me immediately after I messaged her, came over to my house without being asked and slept with me in my bed because she knew I was hurting and that companionship was what I needed most.
She did this even though she was a very talented rower, and had to be awake at 4:00am the next morning for practice. Five years later, this is still one of the most touching, thoughtful things anyone has ever done for me.
Thoughtfulness is about thinking of nice things to do for others, and then doing them. And there is nothing like a close, loving friendship.
