How old people can be a little bit like toddlers

This won't apply to all old people, nor to all toddlers. Actually, it's about just my mum vs my toddler:

Needing help crossing the street

Refusing to listen to advice

They say what they think

Often won't acknowledge when they need help

Thinking that their respective needs are more important than anyone else's

Stubbornness

They nag and nag until they get their own way

Wispy hair

Both probably love me to bits, but can't or won't say so

There are of course, many differences, which is just as well.
