Who would be most likely to be surprised and disappointed if things don't go as planned, an SLI or an LSI? Like if something doesn't turn out the way they had imagined, which happens often.

Example 1: they get really excited about decorating their room a certain way, put a lot of work into it and are extremely disappointed and depressed when the result doesn't match their expectations

Example 2: they make plans to do something special with a significant other, plans fall through due to poor scheduling, they become irreversably disappointed ("the night is ruined"), proceeds to act cold and unresponsive
