A photo of the plant would help. You should acclimate the plant to Full Sun slowly. Compost tea might be a bad idea. They want rain water, distilled water or R.O. water only. No tap or bottled waters.

I wonder if your friend touched all the traps, thinking it was kind of cool to see them close.

VFTs are not like other plants where fertilizer or compost teas would be good for them, though some people report success in very diluted solutions. In general, though, until you have more plants to experiment with or gain more familiarity with growing them, you can follow the general growing instructions that give more happiness and success to your plant.

The steam from the the hot water won't kill your plant, sound like your friend triggered the traps. Another thing, if you used water from the compost to water your Venus flytrap, I suggest you change the soil immediately, the rich nitrogen will contaminate the growing media & will kill the plant. I suggest you by long fiber sphagnum moss, or use the true & tried mixture of 50/50. half part perlite & half part sphagnum peat moss, make sure the perlite & sphagnum peat moss hasn't been fortified with fertilizer or wetting agents; read the labels. Use distilled water, or 2nd choice if that's not available, reversed osmosis (R/O) water.

One more thing, triggering the traps will eventually kill your plant. Th act of closing wastes a lot of reserved energy stored in the plant. The plant can easily tolerate one or two traps closed with no prey in them. But doing it too much will exhaust your plant, stressing your plant & eventually making susceptible to fungus infection. This could result into a smaller weaker plant, or at worse it may die. People have done everything right to grow their plant but the end up killing by triggering the traps frequently,
