I am going to explain what happened as best as I can...
My friend (recently have became friends but she is a devout Catholic and we get along) asked me for a favor. Her family does not live here, so she was visiting them and had asked a mutual friend to take her to the airport the day she left Michigan. This mutual friend was telling me that it was annoying for her because the drive was far, she got lost, etc. (she gets lost a lot and is not good with driving far or directions). Anyway, I had a feeling she would ask me to pick her up from the airport, and she did. She asked me, and I just basically told her the truth and said I wanted to go to mass instead of Sunday, but then I asked her where the airport was, and what city (it is about a 40 minute drive for me, and she lives about 25-30 minutes from my house) I asked for the address, and said I could come if she doesn't have anyone else and some other stuff, but basically i had told her that I would come.
I talked with our mutual friend right after, and was telling her about it, and I told her I didn't really want to, etc. One of the reasons I didn't want to was because I wanted to go out at night, and I knew I wouldn't be able to if I picked her up. Another reason of course is the driving. So, my friend convinced me to tell her no and to just tell her something as to why I can't. I didn't want to lie, but at the same time I wasn't planning on doing what I told her I wanted to do. I did want to get a haircut and hot oil treatment done, but not the day she asked me for the favor. Well, I basically gave that as an excuse, and so I planned on just really doing that. I also told her I wanted to run errands and stuff I needed to do(which I did have few errands to do). I didn't want to lie, but I talked to my sister afterwards about it, and my sister is the type to make up "white lies" to people because she thinks it's more rude to tell them excuses such as mine, which aren't good reasons to tell someone no. I don't like lying, but my sister basically said made me think it was wrong of me to tell her something I truly wasn't planning on doing that day. To make it clear, I said "I remembered I wanted to..." I didn't say I was going to, but I was going to actually just do it so that it wouldn't be a lie. Sorry, I know this sounds confusing, but I am trying to explain it the best way I can. Anyway, my sister kind of made me feel bad (she wasn't trying to do that), but she does have a point about what I did. Was this wrong of me?
To be honest, I also just feel like she wouldn't do it for me (even though I don't know for sure).
