She will forget about any argument when she needs my help lol.
Ignore them.
My sister is 4 and a half years older than me
Just ignore them I barely talk to my brother anymore and he barely talks to me
Siblings aren't that bad also
Silent treatment.
Me too, by 20 months.
I'm starting to think I should apologize. Once he moves I'll probably only see him once ever.
