Totoo bang sensitive yan, o baka gin-guilt trip ka lang niyan para pansinin/tulungan mo? Some people can be quite manipulative, even kids. Either way i'm willing to bet he'll blame *you* for not texting him, even if he picked the fight. Yung tipong lahat ng tao me kasalanan pwera siya mismo.
Anyways, if you think the friendship is worth keeping, just reply in a seemingly supportive manner: "aww, kawawa ka naman", "wow malas mo naman"...that kind of b.s.
In the end he/she either has to grow up, or cut the manipulative crap, if he/she wants to stay friends.
