Blushing in The Lord of the Rings

A quick word search on "blush" in my kindle edition of LotR reveals 12 matches.  Here's who blushes and how often:

• Sam 7x 
• After reciting the Gil-galad poem (p. 186)
• In Rivendell, after taking Frodo's hand and stroking it gently (p. 225)
• After getting himself invited/conscripted into Frodo's quest (p. 271)
• After enduring Galadriel's glance (p. 357)
• Amidst the "praise them with great praise!" accolades to him and Frodo (p. 953) 
• After Bilbo gives him money "if you think of getting married" (p. 987)
• When Frodo praises him in front of Rose (p. 1014)
• Pippin 1x
• In conversation with Beregond, after temporarily forgetting to make sure Shadowfax was taken care of (p. 761)
• Frodo 1x 
• Amidst the "praise them with great praise!" accolades to him and Sam (p. 953)
• willow-trees 1x (p. 507)
• walls of Gondor 1x (p. 751)

(The 12th word match is after Sam's blush in Lothlorien, when Pippin asks him "What did you blush for, Sam?")
