my sons dad didn't get me anything for mothers day but he did call and text and tell me happy mothers day. I want to get him a gift even though he's an asswipe. his first born son. I want to do something personal and special even though he really doesn't deserve it from how he's been treating me. I guess that's how Jesus does us. we get his grace even though we deserve wrath and judgement. so, what are some ideas?
