If one wants to do something, he can be motived by just one reason. But if one not, he can always find thousands of excuses. Does he?

My friend was upset yesterday because of her relationship with a boy. As it in love, if one always be busy to spend time with you. And you sent message, he didn't reply in time. When you asked why, he said he went home late and thouhgt you had gone to bed.

I don't believe it. Do not find any excuse for him. He is just not that into you. Is it ringht?
