Babysitter in trouble 4

Lisa and her babysitter Carissa where watching a movie there a young lady was tied up by a bunch of kids.
Carissa was shaking her head the entire time and said something like:
"that is so unrealistic, these little kids could never tie up a adult woman so tight"

"so do you wanna bet?"replied Lisa.

"okay, I'll take the challenge, but I think we have no rope in these house" said Carissa and was sure that the whole thing was over now.

"wait a minute, I know where my mom is keeping her ropes" said Lisa with a big smile and returns a few moments later with a few coils of rope in her hands.

10 minutes later Carissa finds herself tightly bound and gagged on the armchair with no chance to escape and hearing little Lisa saying that she is going to a friends house by now and that she will return in a couple of hours
