H is pretty solid in the Words of Affirmation camp. After reading about the 5LL, I really understood H's tendency to ask my "why?" whenever we were in an intimate discussion and I told him ILY. It always seemed like the weirdest question to me, especially because he asked it repeatedly.
My LL is more Acts of Service. I commonly respond when my friends are in need by cooking, babysitting, running errands etc. Gifts is most likely a close second. Not expensive or big gifts, just little tokens mean the world to me.
