Suggestion: Take the opportunity offered the next time you tic.
This is one strategy you can use if you currently have a tic that you fear might offend your date.
Talk to a doctor or therapist who knows TS well about how to do this (basically, it involves finding an alternative behavior that satisfies the same urge).
For example: say you have a nose-picking tic — there might be something else you could do with your finger when that urge comes on.
I hate the awkward silences because that is when the Tourette's really wants to come out.
I can never tell how my Tourette's is going to act.
