Chances are, you've probably had the thought of growing old surrounded by people you love the most. Well, these best friends are actually doing it.

Friendship changes as people grow older. When you were young, you often spend most of your time with your friends.

But after college, life pushes everyone to different places, which is later followed by numerous family and work responsibilities that you can't find the time to connect with your college friends.

Some people even move to other cities and forget about their childhood friends.

But that isn't the case for these best friends— they've built small houses (tiny town) close to each other so they can grow old together.

The Tiny Town

Four couples have been best friends for more than two decades, but they couldn't see each other often. So, they came up with the idea that'll let them live as close to each other as possible.

Environmental-friendly homes were everything they were interested in. So, the couples took all their money and built a town near the Llano River outside of Austin, Texas.

The cabins in the Llano Exit Strategy cost $40,000 each and were designed by Matt Garcia. The small houses are efficient and cost-effective.

The cabins have slanted roofs, reflective walls, insulated windows and water barrels (5,000 gallons).

Matt Garcia, the architect, said:

"We just wanted something warm feeling that would offset the coolness of the metal on the outside. It's a high-design finish that doesn't cost a lot of money."

"The reflective walls and insulated windows ensure the heat is reflected and thus keeping the cabin cool even during summer. The interiors have been made with plywood, which has kept the cost of the house low. The slanted roofs have water barrels that can hold up to 50,000 gallons of rainwater."

Take Care of Your Friendships

Here are three tips to help you keep your friends around forever:

1. Be Honest

You can't expect a friendship to last if it's just built on falsehood. Be honest about everything that matters in life, including your past, opinions, and future goals.

2. Grace

Show grace as much as possible by doing good to your friends even if they don't deserve it. Change your expectations to lessen the pressure your friends feel and forgive them before they even say sorry.

3. Make up After an Argument

Disagreements are common in all friendships and relationships. Since you probably know your friends' strengths and weaknesses, please don't take advantage of them.

Learn to apologize when you're needed to, and forgive others.
