+ConnectionPools manage a set of Connection instances. redis-py ships with two types of Connections. The default, Connection, is a normal TCP socket based connection. The UnixDomainSocketConnection allows for clients running on the same device as the server to connect via a unix domain socket. 
+To use a, UnixDomainSocketConnection connection, simply pass the unix_socket_path argument, which is a string to the unix domain socket file. Additionally, make sure the unixsocket parameter is defined in your redis.conf file. It's commented out by default.

+You are not so absorbed about them. You see them for their flaws and perfections. Since you can rely on your instincts and find other pleasures, rather than just within the relationship itself, you understand your partner better. This knowledge will prove beneficial in the way you treat them.

+Being in a relationship can be a full-time job. Sometimes, it can become so overwhelming and consuming that you lose your own voice and sense of ownership. You want freedom and you think your partner is not making you happy enough. You question why you are in the relationship at all.
+
+Yes, we all need that moment to feel uneasy and track our direction in whatever relationship we’re in. These breaks can be beneficial to becoming the person you want to be. Here are some of the positive things that can come out of those moments of indecision.

+Being lost can offer you freedom. You identify your core values, desires, and tastes. You are open with yourself and you can try new things. You understand that you do not have to always rely on your partner. Perhaps there is a movie coming out this weekend, you can buy a ticket and go to the cinemas yourself — something that may have been unheard of for you in the past. Being forced to find this independence can make you a stronger person.
+You can disconnect. You are no longer driven by the interests of your partner, but by your own desires. This means getting back to the basics, like reading books by your favorite author, exercising, eating your favorite meals. When you return to these ideals, you are strengthened and become a better you.
+
+People think that being lost in a relationship signals doom for that relationship — it doesn’t. It all depends on how you manage this necessary stage and work towards making the most of it.
