"The friend who holds your hand and says the wrong thing is made of dearer stuff than the one who stays away," by Barbara Kingsolver is one example of a quote for a friend on their birthday. Another is "With mirth and laughter let old wrinkles come," by William Shakespeare.
Birthday quotes for friends may be funny, full of gratitude or inspirational. They are a good way to add a special touch to a gift or card. Friendship quotes may also be engraved on homemade gifts, such as handkerchiefs and T-shirts. Other special birthday ideas for friends include setting up a treasure hunt and having a picnic.
