In hindsight, how much did you like your younger self? If present-you met your younger self (say, age 10) from an alternate timeline, do you think you could be friends?

This will not affect your original timeline.

And lets take take this hypothetical a step further:

Sceanrio 2:
Say, in the alt-timeline, present-you arrive in the year when past alt-you were 10 years old, your original parents/guardians/caretakers dies for some reason on this timeline, would you care enough about your alternate-self help them? Like take on the role of a parent/guardian in place of their now-dead parents? (Basically, its a roundabout way of asking: How much can you tolerate yourself?)
