Remarkable, unbelievable, and unreal are all ways in which someone could describe something truly amazing but also, much like in your case, something totally bizarre!
Just kidding with you, buddy! I’m sending my best wishes to the birthday boy today!
Happy birthday, pal! You know that I’m always looking out for your best interests, so just take care today when you’re trying to blow out the fireball on your cake!
A long distance friendship is the most special kind of friendship that exists, as it’s proven to be strong enough to survive the miles. Happy birthday, bestie.
