The Botanic Garden has activities for kids. This one caught my eye. Old English teachers never retire.

Now I know why I like you so much! An ever downward spiral isn't it?!

I love finding grammatical errors — old editors never die either!

@grammyn @wiesnerbeth Glad you both understand. My kids and my husband roll their eyes when I point out something like this.

@eudora my family has come to expect it from me and actually find the errors too!

@grammyn You've taught them well! Actually, one of my sons refused to consider a school for his children because they misspelled "calendar" on their website.

@eudora oh my kids roll their eyes too — I once spent an entire dinner critiquing a help wanted poster in McDonald’s.
