a small fib

so i was at the grocery store today and there were these new flavor of chips that i wanted to try really bad but my partner and i are trying to stick to a budget so i lied and said i already had some at home this feels so silly like why do i care so much it's just chips you know? but now i feel guilty for lying even about such a small thing which is stupid i mean its not like im cheating or anything but the guilt weighs on me more than it should lol
