There are many ways to say thank you and I have read all but one way. Months ago in an email. it stated that one way to thank a soldier (is not wanting to speak, bashful, or whatever) is to place their right hand over their heart and just nod. And then I also heard that one should wear a red shirt on Fridays for the brave men of the United States. Yea, my hand is on my heart and my red shirt is ironed. God bless them.
