Any social event you go to will always be great, or you get anything you could want to enjoy alone time

The social event counts as more than 4 people attending. Everybody will get along, enjoying themselves and making good conversation. The exception is that those who already don't get along aren't going to magically become friends.

You also can't use this to just do whatever you want, if you do something weird people will comment on it (this doesn't apply to things like if you are awkward or have bad social skills).

The alone time option means you get whatever you could want to enjoy your time by yourself.

20k gaming setup? Done.

Skydiving? Done.

Only you will be able to do these things, and you can't pass on anything you get to other people via inheritance or such.
