More Awesome Than You!

I'm trying to erase the "First Kiss" memory on a sim. I accidentally clicked the option and didn't get a chance to take a picture. I am assuming that erasing the memory on both sims will make "first kiss" available again; also that modifying memories is safe and something you can do with limited technical knowledge and SimPE.

You can delete any memory that is 'visible' in the SimPE memory editor without problems.  I'm forever poking about with the memories.  I'm not sure whether the first kiss will be reset.  I think it will be but I've not actually done that myself.  Remember to delete the memory for first kiss for both sims involved.  I have a feeling (again not personally experienced) you will only get the little video if the sim initiating the kissing hasn't already had their first kiss.  You can delete the gossip memories too (in blue, in italics, invisible) but leave everything else alone unless you know what you're doing. 

I can confirm: the first kiss is reset; you actually need to delete the "had very first kiss with $subject" and all the "kissed $subject" memories for a proper reset. If you delete only the "first kiss" one, for instance, the sim will have the option to kiss as usual anyway, but the next one it will kiss will grant a new "first kiss" memory with him too.
The same happens with woohoo and first woohoo memories.

Since the OP had his question answered, allow me to highjack this thread a little.  Does the cascade deletion does what I think it does?  If, let's say, I do a cascade delete of kissed $ubject, will it delete it for all the sims that share it?

"Cascade" delete is a crude attempt to remove a memory and all its associated gossips.

If all you want is a picture of the kiss, you could use the all options cheat thingy.

When you call it crude, I am correct to assume it does not work very well?  If so should it be avoided?

That's a good idea Gwill... of course now I'm determined to figure out how to do this properly...

I must be missing something because whenever I go in to try to edit memories I see nothing but blank memories and gossip. In-game, the sims' memories are just fine. I think SimPe mustn't be reading them right but for the life of me I can't figure out what the problem is.

I think that's because you have a version of SimPE which is out of date for whatever your latest EP is.  I've had that when I've installed a new EP but not the new version of SimPE for the EP.

My latest EP is Seasons... I just downloaded the latest version of SimPE and still get blank memories. Bleh.

I'm going to bump this once to see if anybody has any ideas about why I might still be having problems with SimPe. If not, I'll just ignore the memories and cheat my First Kiss picture.

Point taken.

*goes*

Ugh, I hate memories.  I tend to get all OCD and freak out when a Sim gains an memory that doesn't fit my master plan. 
Sim PE's memory adjustor has always worked for me, though it's been a little wonky lately. 

Well, in TS3, there are no memories, there is only Zuul.
