I sympathize with her too (didn't mean that to be an 'old people' joke...'modern life' was supposed to be alluding to the state of car seats today). At some point, we've all been there with a stubborn car seat buckle, and every friggin' one is different, and they're all very particular about hitting the right spot (which I s'pose is good in some ways, prevents unintended unlatching).
Was posting that from my phone at the library, so it was short, but she was all awkward when asking, embarrassed when I came over and popped it first shot...I kept saying "It's okay", "no problem" and finally "Don't worry, they get the best of us all at one point or another."
There was probably a time where I would have been judgemental, but that was before I had worn those shoes myself...and it's much more pleasant to go thru life trying to give a little grace than getting upset over small things. When I heard the "Excuse me, sir?" and looked up to see the look on her face, standing by the car door, I thought "grandma's taking kiddo to story time, that's nice! I'm guessing she can't get the carseat undone....yep"
