Should i bother sending this chick i met in camp an email?

here is the story. She lived in Poland but as far as I now she is currently in NYC from the summer to work in AHRC. She was in my cabin in camp and there was no one else from NYC there but me. Problem is she is 28 I am 20 but she looks like she is 20 but age is still age. And I told her if she needs something she should call me which didnt happen yet. For the first few weeks back I couldnt forget her but now gradually she has been forgotten. So I ask u should I bother emailing her (I dont even know if she still visits her polish email) or just let it go and hope that everything is good and if she needs something she will notify me.
