A minha sugestão também é policia, mesmo que possam haver poucas provas neste momento, na eventualidade de algo pior acontecer, já existem provas de que ele te andava a seguir.

Já que gás pimenta não é legal, como foi dito (mas a verdade é que se arranja), pode ser sempre andar com um desodorizante de viagem, tipo este (já vi à venda do Continente).

It's hard to come by, but [here](IRISCH MOOS by Sir for MEN: SHAVING SOAP STICK 3.5 OZ https://www.amazon.com/dp/B008B8DP00/ref=cm_sw_r_cp_api_26gRzb4JMS1ZA) is an Amazon link. The deodorant stick looks EXACTLY the same, so beware. I just accidentally grabbed the wrong one.

Reminds me of that Bod man body spray that also comes in like a household cleaning supply spray bottle.

I've gotten many compliments on this. It smells so good, and it is really inexpensive.

This stuff smells great

If you have a wishlist going, on Amazon there are some nicer, less expensive ones (that I think probably smell better). Like this one for example. Hopefully another santa can grant this wish there.
