Descriptive is nice. The thing is, when you use 'may' or 'might' it no longer stays as objective. There's no necessary big rule, but generally, the more precise/descriptive you are, the more it helps.
The child misbehaved and got on grandma's nerve. It might not be the truth (that's a journalist's job), but you are definitely portraying a more emotional story ;)
Grateful for your help. Been learning lots from you. :-)
