Why does it matter

I seem to have this pending question anytime I am listening to someone speak. Why does it matter ?? Mind you I don't mean this in a derogatory sense. I truly mean it in a question. Why does it matter ?? Why does what I say matter. Is it important, is it a vent, will I need this later, does it fall under the 5 for 5 rule. I have a real love/ hate relationship with people. Love to be with them and hear their thoughts and ideas and have always enjoyed a laugh where you can't see because you're crying. Those are all on my terms. The hate part of my relationship with the human race is when I don't want to be with anyone but my kids and the MB. When I am in this mode people really annoy me. Let me clarify I am a stay at home mom with my own business as I said before I do LOVE people. However I am becoming increasingly annoyed with this question.
"WHAT ARE YOU DOING?"
Now this question takes on many different avenues. For instance:
"WHAT ARE YOU DOING THIS WEEKEND?"
"WHAT ARE YOU DOING TONIGHT?"
you get my drift. This is a loaded question for so many reasons. I want to be honest when I answer it. I want to be able to say oh nothing or we're going away for the weekend. I really want to be honest with the first part of "oh nothing" however this is like stepping into a bear trap. Because what usually follows is "well we have plans and were wondering if you could watch the kids or hey I thought we'd stop by". Can you hear my pain!! I tell them nothing because I am thinking hey maybe this will turn into an evening out or something really fun. No instead you want to dump your kids on me. Now let me tell you I also enjoy having friends children over when it is on my terms and I have never turned away someone in need of help. This whole dance annoys me so much that anytime I need a babysitter (which is usually Oma and Opa). I always start the conversation with everything up front and make it abundantly clear I have other options.
Okay now onto the drop by. Love my friends don't love the dropbys. For so many reasons. I cherish every moment I have with my kiddos and I don't like it interrupted. I like to maybe have myself and or my house pulled a little together for company. This also seems to turn into the unending play date with me schlepping food to all the kids. My MB always tells me that it's because I am such a great host and no one wants to leave. I appreciate this and if you are an invited guest I very much feel that way. I am prepared for your presence and am ready to devote my undivided attention to our conversation. I'm not worried about what I need to be getting done or how I am going to get it done now between when the kids go to bed and before I drop.
Agree with me or not. What kind of person are you?? The inconvenient question friend or the I can think of more than myself friend??
