<human>: Can you summarize the given text in a few sentences?

Ok. I'd like to start out by saying that we have been friends for about 10 years now. Best friends for most of those ten years. So tonight I got off of work and I did the usual, call her to see what she was up to but I didn't get an answer. I didn't think anything of it and I figured I'd just call when I get home. I do and still no answer. 20 minutes no answer and I give up and go hang out with some other people. These people are very close neighbors of my bff. When I drove up I noticed her car wasn't there and I figured she was just busy and will get back to me later. I go hang with my friends and then She texts me and says that she's with her mom at a local grocery store nearby (driving, walking is a hike) and they started walking back. She said she'd join us soon. I thought that was weird because her car wasn't home and she never let her mom in her car. I let it go. About an hour later I came back to my car and still no sign of her car. I then left to another location and stayed for 45 minutes before she arrived. When she came she had her shirt on backwards and was acting differently.. mind you I've known her for a very long time so I know when something is different. We hung out for a lil and it was cool, but she kept emphasizing her mom and the walk. I was very suspicious but I left. When I got home I confronted her with how I didn't see her car and she said she was lying the whole time. I tell this girl everything. We are seriously the closest friends.. but does she not think that way.... The fact that she was so sneaky got to me.. and that she kept on insisting she was not lying even when I told her "I just want to let you know that you don't have to not tell me things..."
<bot>: I feel betrayed by my bestest friend ever in the world not because she got her pencil sharpened but because she was so secretive and lied about it to me... I dont know how to feel about it... Thanks for reading
