I think the 2 errors are 1. The word Myself should be replaced with me. So it would be “more presents than she gave me”! 2. The then needs to be replaced with a than. Hope this helps.
The "then" should be changed to than and "myself" should be changed to me
Explanation:
Than is used when you're talking about comparisons; then is used when you're talking about something relating to time. And "me" sounds grammatically correct.
I usually tell them thanks for your input even if it really wasn't needed or wanted then I take a deep breath and continue about my day. I could improve by trying to see from their point of view.
