Can You Really Fall for Someone at My Age?

I never thought I'd have a crush again, but here we are. Since I started helping out at the community center and met Alice, this weird feeling just won't go away. It's like when you were young and everything was new. Every time I see her...my heart skips a beat...she has this laugh that makes me want to grin from ear to ear. But of course, I keep my distance, pretend it's nothing. Should I tell her? Do people still fall in love at seventy-two?
