[well, aren't you just the ideal! you are also someone Effie knows is helpful, so she approaches you. her exposed skin (which is pretty much all of it save where she is wearing underwear) covered in drying mud. it's sunscreen, improvised!]

Hello there, Sif! Are you-- you don't burn? How lucky! I saw a tribute cover himself in mud once, and it occurred to me today that it's a good idea. Otherwise, I'll be stuck in the shade all day!

[and being in the shade all day would mean very few people to talk to, and Effie does like talking to people!]
