ENTps are supposed to pursue things in front of them or in their head while forgetting about their bodies, like explorers in some cold place who continue even though their limbs are falling off due to frostbite.
ISFps would ideally like to go on such pursuits, but they are grounded more in their bodies somewhat. Both ISFps and ENTps like to chill and explore new things, so it isn't necessarily surprising when, for example, an ENTp tells a ISFp to relax and stop getting so stressed, or for an ISFp to inspire a new venture for an ENTp.
In the wikisocion pages, the ISFp Si Ego description says that ISFps often feel they are in a hurry, and must do everything at once. This could be a good description of an ENTp's Ne too. Both types are able to make each other relax, it's not just a thing, and both types are able to help the other prioritize. They both find each other interesting, and do not consider each other's advice irritating or painful. The result is lots of children.
INTjs are supposed to be all logical, you know. But ESFjs often seem to make good sense, you know. ESFjs are capable of intuiting how INTjs feel so that the INTjs needn't reveal too much about themselves, and INTjs are able to get a good gist of what the ESFjs mean to say. They can speak passionately about things and not get tired or scared of each other - it is all good-natured, and can be both serious and light-hearted. ESFjs are supposed to be good with people, but they can also feel lonely or uncared for when they are socialising. They paradoxically, perhaps, enjoy the quieter company of an INTj, and the INTj would certainly prefer to be with an ESFj in a social setting. INTjs can attempt to cope in a social setting, and may do quite well, but if they miss a minor turn in mood and fail to match it, they often find themselves lost for words or even cruelly neglected while others talk too loudly or incomprehensibly. (If others start talking about personal matters, an INTj may be able to maintain a conversation, but during such conversations, an INTj will pine for an ESFj - INTjs don't really like to talk about specific personal details or the private lives of others, causing them to talk abstractedly - they realise this will be unacceptable, so they may withdraw before massive fail). INTjs don't neccesarily mind mindless twittering, it just seems to be extremely problematic and potentially a waste of time. Also, ESFjs like to say things from the heart, which means they may be at a loss to be completely logically coherent all the time. Which is why an INTj and ESFj make such a good team together and have lots of children.
