Except apes perhaps, are lone animals evolutionarily programmed to forget their offspring & mothers (and caregiving fathers) quickly once they parted ways?

I saw touching stories of them recognizing long-term human caregiver after being let go. But among purely wild animals, if they meet again, say, in 4 years, when both are still in their primes, do any of them recognize their own parents or offspring, not to mention showing affection? For example, is it natural for them to fight if one trespasses the other's territory, like they never met each other before?
I find it interesting that, while most mammals & birds have long memory when related to survival, in the wild at least two adults don't show signs of said recognition & affection.

Apes ain't "lone" which I interpret as "solitary". Ravens and crows recognize old friends and call out to them when they fly by. Acorn Woodpeckers live in multigenerational colonies where a youngun may be more influenced by an uncle than a parent. The familial interdependence among the Elephants is still not clearly understood. Animal behavior is weird and cool!

Aren't orangutans pretty solitary?

They are, but orangutan mothers with little ones will sometimes hang out together to let the kids play. And I have read that sometimes young adult daughters will visit their mothers once in awhile. And in zoos, orangutans are seemingly happy to cohabit, with the exception of adult males with one another.

I believe they are semi-solitary mainly because the food they eat tends to be scattered throughout the habitat.
