Love is patient and kind; Love is not jealousy; Love is not boasting, not puffed up;
Don't do rude things, don't ask for yourself, don't be provoked, don't think evil;
Don't be shy, don't seek your own interests, don't get angry easily, don't count the evils of others,
Endure everything, believe everything, hope everything, endure everything.
Always tolerate, always believe, always hope and always endure.
Love never fails.
Love never stops.
From the original English text, not doing shy things means not behaving rudely, which literally translates as "not doing rude things" means not acting rashly.
