persahabaTannnn

Bukan Atas apa atau dasar apa kita menjadi seorang sahabat

Tapi itu dari hati,,,,,

Ketulusan untuk berbagi dan membagi

Menyejukkan bukan membekukan,,,,

Menghangatkan bukan memberi rasa panas,,,

Sahabat adalah,,,

Seseorang yang paling tahu hal buruk dalam diri kita,,,

Seseorang yang selalu marah saat kita berbuat salah,,,

Seseorang yang selalu berusaha melukiskan senyum dibibir kita

Seseorang yang selalu meminjmkan bahu untuk bersandar

Persahabatan itu ibarat tangan dan mata

Saat tangan terluka mata menangis

Dan saat mata menangis tangan mengusap air mata
