["I was happy that I called my mom in time for her birthday this year.  I felt good about myself that I'm a good son who still keeps in touch with his mom.", "Aw, that's so nice of you! I bet she appreciated it", 'Thanks :) she did a lot, actually']
Keep doing things like that! Parents appreciate little thoughts like that more than we know
I was happy to call my mom just in time for her birthday this year.   I thought I was a day late but I called right on time.
