MEMORIES

Think of memories you've experienced with them that are packed with emotion - if you get emotional writing the memory, chances are they'll find it emotional too. Reminiscing can bring back so many good feelings.

INSIDE JOKES

An inside joke is great evidence of a lasting bond. Try and think of some old ones, this will make them feel nostalgic and will unquestionably put a smile on their face (maybe even a few tears).

KIND WORDS

Tell them what you appreciate most about them; how they always seem to cheer you up and are always willing to listen to your problems. Remind them of their best qualities; funny, wise, caring, helpful - they'll really appreciate it.
