Long lost friends
It can really suck when you lose touch with someone who you were really good friends with once upon a time. It can be really hard to find someone else that you have a similar connection with and you find yourself thinking about that lost friendship often, wishing to get it back.
Thankfully, there is something called the internet now, so people who lost friends years ago have a chance to reconnect with them, something that was much harder to do years ago. Now people from all over the world are finding their ex-best friends from middle school and we couldn’t be happier.
