his best friend
she was a happy dog named happy dog, but she is not the one this title refers to... his best friend was a mismatch because to her, he was the love of her life, the one and only love she would treasure for all time... unfortunately, he already had one of those (or something like that), so she was his best friend, the one who cared more than anybody else, the one who wanted him more than anybody else, but unfortunately, the one who wanted him to be hers without giving him what he needed... so maybe she wasn't his best friend, maybe she was a love-struck child who would not compromise, maybe she knew she was not the love of his life so she held back what he wanted most, someone to share his dreams, his creative play, his love of words, his passion for life, and his search for the one (all he ever needed, remember?)... but she wanted to be the one and even as she did not give him the sharing he wanted, she would not let him go, even after he finally left... they bought the house together after he moved a thousand miles away, who was using whom... she was trying to hold on to him, he was trying to balance the books, but it was a mismatch and ended as most mismatches do...
he wonders where she is now and hopes she is happy... she wonders if he ever cared...
