"pretend" would be the intentional variant of "simlu", so:

simlu: x1 seems/appears to have property(ies) x2 to observer x3 under conditions x4

mlugau: x1 makes x2 seem to have property(ies) x3 to observer x4 under conditions x5

sezmlugau: x1 pretends to have property(ies) x2 for observer x3 under conditions x4

Then we have:

ro ma'a ckaji lo se sezmlugau be ri
Each of us has the properties that they pretend to have.
We are what we pretend to be.

"Love all" would that be something like lo ro prenu se prenu

"Love all" in what sense? Is it an imperative (telling somebody to love everybody)? Is it a claim ("I love everybody")? Is it a greeting ("everybody sends their love")?

I haven't read the novel in question (I've only read a few of Vonnegut's). Here's the first translation that occured to me, something like:

.o'i lo'e xanri pu'o fatci

(Caution! The typical imaginary thing is later a fact.)

Is that missing something from the original about personal identity? Perhaps then:

.o'i lo'e nu lo prenu cu se xanri cu rinka lo nu py. le xanri cu binxo

(Careful, the typical event of a person imagining is the cause of an event of them becoming what they imagined.)

There's surely no close Lojban equivalent to "pretend" as meant in the book, or in English in general. Lojban's vocabulary is still quite small, and growing only slowly. If you have a clear vision of a specific meaning, though, there are plenty of lujvo waiting and ready. Stylish new words with rich meanings are just what Lojban needs these days, I think.
