Distrust all those who love you extremely upon a very slight acquaintance and without any visible reason. That use you and don’t even leave the last piece of toilet paper. © Unknown

This quote is rather humorous yet insightful observation! The point of view about being cautious with those who quickly profess their love and those who use you without consideration does resonate with some biblical wisdom.
Here’s a related verse about discernment and understanding people’s true intentions:
“Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. You will recognize them by their fruits.” – Matthew 7:15-16
And another about how to treat others:
“So in everything, do to others what you would have them do to you, for this sums up the Law and the Prophets.” – Matthew 7:12
It’s always wise to be discerning and to value relationships that are built on mutual respect and kindness.
