Keeping score in a friendship turns every favor into a bill.

The second you start tracking who did what, kindness turns into accounting. You gave them a ride twice, so now they owe you, and they can feel the invoice even if you never say it out loud. Friendships do not survive that for long, because nobody wants to be in debt to someone who is supposed to like them.

Give what you can give without needing it back, and when you cannot, say so plainly instead of saying yes and adding it to the tab. One honest no now costs less than a year of quiet resentment.
