How to maintain a long distance friendship with your best friend
Text your friend/s every day and ask them how are they doing.
Ask questions about their life, like their school, work, or relationships. Even if they've made new friends, try to always support them by giving advice and talking about their problems.
Always be there for them, and try not to ignore their texts if they text you. Call your friend (s) often and try to always sound cheerful when they answer your call so, they won't get bored while talking to you.
