I've seen this movie so many times that I remember every little beat to it. This is precisely the moment after Harold finds Maude modeling for Glaucus (spelling?) and she calls out "Harold?" and he replies, surprised, "Mauuudddee!" while the wind is practically blowing him out-of-frame. I love that moment.
The blue lettering is kind of gross, sorry, I don't understand (color) marker pens at all.
