Aretha said it best "R-E-S-P-E-C-T"

Ive been told I make mountains out of mole hills and mountains out of mountains. What Im trying to say here is I apparently cant distinguish between the big issues and the small. However, I feel when it comes to how I am treated by others I deserve the quality of care and respect I give to them. Many a times have I been burned by being taken advantage of because of the mere fact that I do care and want to help others, especially my friends, as much as I can. Whether it be time or money, I try and give as much as possible all the same. What brought this post on, you may ask? Well, a friend of mine watched my children for about an hour and a half two times so I could go do interviews for my current place of employment. In return I told her I would watch her children when she needed it. She asked if I could watch them on a Saturday night as she was going to be taken out by her boyfriend. I told her that would be fine as our children could play together and have fun. As it turned out, I did not have my children that night. So, I asked to watch her children at her house so they could play with their own toys and sleep in their own bed. She said she was not comfortable having people in her house when she wasnt there. Now, just setting the background for this-she has an 18 year old room-mate that lives with her and has friends coming and going all the time. SO, I didnt understand why she was not comfortable with me staying over there. So, she brought her kids over to my house without calling or anything and I had no idea as to what time this was all going to take place. I happened to be in the middle of an important conversation (or like argument) with my childrens father when she showed up. I was unprepared and had my emotions everywhere as the conversation had left me upset. I told her I didnt know she was coming as I hadnt heard anything from her and she decided to get snippy with me about the whole ordeal. So, she leaves and says just forget about it. I get a phone call about an hour later from her boyfriend asking if Im going to watch the kids or not. Now bear in mind that I was raised pretty sheltered and isolated from the real world. I dont do well in social settings at times, especially if my emotions are very tied into the situation. So, I say yes that I will watch her kids. So, they come back over and drop the kids off and then proceed to inform me that they will not be picking up the kids until 11:30 the next morning for church. This is the part where I become speechless. It all of the sudden makes sense as to why she wouldnt be comfortable with me being in her house. She didnt want to come home after her night out and deal with the children the next morning before church. While I would of probably agreed to it if I had known beforehand what she was wanting I felt very disrespected for her lack of thanks or asking if the situation would be ok. I would never have done this to her or anyone for that matter and I certainly would of asked them to stay at my house as a matter of respect and appreciation. So, the next morning comes and she comes to get the kids and is quite huffy about the whole ordeal. I guess I had been pretty obvious about the fact that I was pissed-but yet again did she care when she dropped them off? No. Did she call or text and check on her kids the entire time I had them?No. So, I conclude from this situation that she has no respect for my time or friendship by this. I am one that can not let things slide if it is hurtful to me as far as my dignity or self respect go. Am I making a mountain out of a mole hill? Shouldnt that be up to me to decide?
