I will talk about moment killer because it happens every one of every day in our lives. You may have encountered in one point in your day whether it was in the work, friend meetings, reunion, or chatting with a close friend but you may consider something that would happen and it is okay. For me, It is very annoying and frustrating for many reasons. I want to list some of my reasons that I feel; it is important for people to know.
In the work, you have your let say 15 mins break and you are talking with your collogue about very important matter or having a conversation about an event that happened the last days, about a book that you both read, you wanted his advice about a life matter, or planning for something interested and we both are trying to decided or getting more involved with the conversation, and someone came and said something irrelevant to your talks and ruined the whole conversation. First, you would lost the 15 mins of your break and then lost the whole conversation. You wont have the same mood to continue or the same enthusiastic. I am sure that you have or will have been in the same situation like this many times. In this case, you can excuse yourself from this because the third person will have already choosing a different topic and started talking about it. Your day is ruined.....
In friend gathering or family, your friend came to talk about her new boyfriend or updating you about what is going on with her and because it is very private, you would prefer to talk to her separately away from other friends eyes or ears. You and your friend in the middle of talks and she reached a very excited events and you are about to comment to these events with vey very good words and motivating her to take step forward before the words come out ......... bomb another friend comes to ask you if you want tea or a coffee. Uffffffff, every word, the motivating speech that you just prepared carefully in your mind is gone. You will be like what just happened, and believe me, you wont remember anything even if it was only one word. Form me, it would be depressing moment.
This one is very different because this time is not an outsider who would ruin the moment but the one and only who is involve in the conversation. You would talk to someone who is very dear to your heart and you want to tell him how you feel towards him with passion words and phrases. You want to show him that you are very important and you want to make sure that he/she knows. You start with magical words like "we are guiding each other and you are my light and shine in this world." You are overwhelmed with beautiful feelings and your voice is changing its rhythm. The inspiring and the spiritual words are flowing from your mouth and all of a sudden, you hear him saying "bad networking, let me call you back," my moment is fatal, RIP. How could you do that we're having a moment here, and you did ruin it. You killed it with a cold blood. What should you do? in this case, forgiveness, ignoring or angry would be the right act?
To sum up, your moment killer would be anyone and killing your moment could happen every day.. Sometimes, it will happen in a funny way or could ruin your whole day. It depends on your perspective and the way you handle it.
