Simply and succinctly enough, these are the five main ways to love people overall (with a few examples):
words of compliment (praise, respect, esteem, honor, etcetera) - "Wow, I so appreciate your hairdo! I think those colors are fantastic for you."
acts of service - A group of travelers within a national park, myself included, stopped and gathered to both enjoy a sunset, good conversation, and to cooperatively change a family's burst tire.
gift giving - Our youngest brother and our sister-in-law got me a hoodie once. It was nice. I liked it.
permitted intimacy - "May we share a hug?!"
quality time - An example of this is when a group of my friends and I got to float on inner tubes gently down a river in summer.
