Maybe the fact you verbally told him you need him shook him off his nice comfy arm chair he has been sitting his b@t the last year or more, and suddenly it...hit him!!!! : Lisa is human after all and she needs ...ME? And I failed to be there? What an a$$ am I?
You never know what crossed his mind (a bullet if I were close and owned a gun) but I suppose you "needing" him is rare. Maybe the not DBing him wasnt bad after all...
