In my impression, people who like folk songs and people who sing folk songs all play guitar, so I will give it to my boyfriend. Those who used to like folk songs will give her a guitar accessory. I might buy him some folk songs to sing. Send him a postcard of his favorite folk singer and grab a photo signed by him. You can send him a wireless Bluetooth headset, which is to give him a better sound quality and make him think of you more when listening to folk songs.
