Frequently Asked Questions:
Q- Who is this?
A- Who am I? You’ve reached out to me and I’m as confused, frustrated and surprise to hear from you as you are (if not more). So to answer your question, I’m a stranger.
Q- Is this Alexus?
A- Yes, this is Alexus, but obviously not the one that you’re expecting (that also includes: no, I’m not in your school and please see FAQ: part “Who is this?”)
Q- How do I stop texting you?
A- Whenever you’re texting don’t just type in “alexus” into a “to:” field, but a phonebook entry and compose your message from there, it’s that simple! ;-]
