Hi Dominic,
Yes, they are unpleasant excuses for sure. Just make sure that you aren’t asking to meet up with them too soon though.
Sometimes, people on dating sites will give the line, “Life is crazy for me right now,” when they feel uncomfortable about you asking to meet up with them too soon.
Always protect yourself from the start by asking each person you begin a conversation with about what they are looking for at some point during the course of your conversation.
This saves you a lot of time and energy by weeding out those who aren’t at a place or time in their lives to take anyone else seriously as far as hooking up or romance is concerned.
