Describe a good parent you know.

The good parent as I know and I'd like to talk about is my friends mum.The reason why I want to talk about her is that my friend aways told me that she has a very good mum,until I meet her mum,I know realse ,she is right.
My friend and me known each other in our university (you can use it a simple present tense),we are in the same major and same class.She is not living in GuangZhou,so during the period of school I have no chance to meet her Mom. At the graduation ceremony, her mum came ,of course ,we met.
Her mum is a beautiful women with black long hair,and she is really nice and polite as I know (Better if you use , i observe). She’s just has got really good manners.To give you for an example, she always says thank you to people, even for small things the slightest thing. For instance, I’ve noticed that whenever we’re eating at a restaurant, she will thanks the waiters and waitresses every time they bring a dish to the table( It is a past simple, it can not be future). A lot of people probably think this isn’t necessary but I’m sure the waiters and waitresses really appreciate it because it doesn't happen with them too that often.
So I think she is a vrey good parent as I know.
