Disappointment

Have any of you ever had one of those times when you were really impressed with how someone was and then they go and totally disappoint you? Say, for instance, (and this is just theoretical) your sibling is invited to the geography bee. Wouldn't you be really proud of them? Wouldn't you encourage them to do it? Of course, if you were a good brother or sister. Say they then throw away that opportunity by not even showing up. Wouldn't you be really disappointed in them? I mean, how short sighted is that? Extremely, huh. That's all I really wanted to rant about. It' s just that someone really close to me just threw away an amazing opportunity.
