Lord, make me an instrument

Since I have moved back to Ely I have kind of felt that I haven't been taking time to serve others like I should.  I know I should just do it, but it seems I am so busy it is difficult to just get my visiting teaching done.  I often think I should call this person or that and invite them to attend an activity with me or such, but for one reason or another I do not follow through.  At times I feel I have lost the ability to hear or feel the promptings of the Holy Ghost.  Whenever I think this, the thought comes to mind that I am serving the primary children each week through the efforts I put into my Primary Chorister calling - but some how I still feel I need to serve the sisters more. 
Last saturday we had a stake RS activity and as usual I thought of several sisters I should call and invite, but didn't do much as I was busy preparing for a class I had to teach at the activity.  I arrived early set up my class which wasn't until the afternoon.  Looked for a few sisters I might know and sat at a table waiting for things to begin.  Soon I saw a sister from our ward come in, she is a good friend of mine, but is an older sister.  She looked around and saw most of the tables that had people at them were full and didn't see anywhere inviting to sit - She headed out to the other side of the cultural hall.  I tried to get her attention to sit with me as there was one seat open.  She kept walking and I thought perhaps she was heading to the bathroom, but for some reason I ran after her and told her to come and sit with me.  Which she did.  We had a little breakfast and a great opening speaker and then we headed off to classes.  When they announced the classes I thought none of these are for my friend as she is great at all these things, but she attended them anyway (always a great example to me).  After the first class I didn't really see her the rest of the day and I went on with the things I needed to do.
At church the next day she handed me the following note:
Thanks for being a friend yesterday and sensitive to the spirit.  I would have gone home.  I've lived here all of my life and have never felt so detached from everything as I have lately.  Your kindness was felt deeply and appreciated.
Now I don't include this to toot my own horn, only to realize that sometimes we are instruments of the Lord in small ways that we may not even recognize.  I remember thinking after I had chased after her, "Why did I do that so abruptly?" as I was in the middle of talking to someone else.  Yet if I hadn't she would have headed out the door.  Most of the time we don't receive little notes letting us know we were an answer to someones need and so we don't recognize that the spirit really is working through us.  So I guess we just keep trying and doing our best.  As I was an answer to her, her note was an answer to me that I am still worthy to feel the spirit and act on those promptings even small ones like this.
