Paying my respect

So my bf and I plan on traveling 3 hours to see his brother grave this Sunday. He really wants me meet his brother because how close they use to be. I want pay my respect as much I can and surprise him a lil by doing this.. I planned on bring a blanket for us, buying some flowers for his brother, and tissues for him(he warned me he going cry). I was wondering if I should bring anything else to make this visit a little easier on him? Or if I have any Honduras lady’s on here. Do you guys pay your respect differently than we do here in American? If soo how?

-Thank you.
