I stole money from my nana's purse once to buy a usb
I think you should tell me the whole story about the USB
Oh yeah, well I gave her the USB drive as a gift.  It contained some software that helped her to work faster.
You shouldn't steal money from family members, even if you are using it to buy them gifts.  It would have been just as thoughtful to show your Nana the software, and let her buy it herself, instead of lying and stealing.
Yeah okay, you're right.
I'm glad you you got my point. If your nana got to know about your theft, she wouldn't be happy about it. I hope you stop stealing from now on.
