There will always be past memories of important and significant events in your life. If they interfere in your life or stop you from doing things then they should be addressed.
We are highly emotional beings that record our experiences. Highly emotional experiences will resurface if triggered. Some can be unhealthy if disturbing your normal life. But it is normal to reflect on past memories that are meaningful to us personally.
Some users may look into what the base was and feel discontent with how everything is going. And are not used to the new members rising up almost everyday. If that's the case. Don't dwell in the past. It can only cause problems in the future. And can even sway your emotions further. I only been a member for a month. And a lot has happen since then. There are still some really sincere members that want to do good for this sight. It does not have to be the end, we can enjoy Naruto for it's worth. Try to view things for the better. And this site is really awesome! Just got to deal with people. Like we always do.
