Gift

Yesterday, I checked my son's exercise book and it really gave me a big surprise.  We sent he to attend a tuition class and then seems we forget all our responsibility for his English grammar.

The exercise book now he is working is on the second book he got, he finished one before, and the tuition teacher give him the second one just to repeat. But i found he still has average 4~5 incorrect answers per 10 questions.  Oh my god, it is time to intervene myself now!!

It lets me think over and over the question:

As parent, what can you give to your child as the best gift (apart from the material stuff) and how?

Knowledge?
Skills?
Tips?
Experience?
