Hi Waseem!
( @johnny )
I asked around in your town on facebook and by email and I got a few suggestions =)
Usually I suggest to just show up in a pub bar (Kneipe auf deutsch) but some said that it might be a bit difficult there. I would still give it a try once.
I would suggest to go and to language school ( Sprachschule ) whether they have some language exchange evenings ( Stammtisch ) going on that you might be able to join.
This is a Stammtisch meetup that gets organized in your city and might really worth give it a try!
https://www.meetup.com/new-intown-freising/events/235354956/ It took place last week and perhaps the organizer are going to organize something new soon. Try to get in contact with them
( this one is the link to the next one they are organizing on the 21st of this month
https://www.meetup.com/new-intown-freising/events/dlxsxjyvqbcc/ : drop by and get wild on your German ahah )
I would also take a look at the events and workshops taking place in the city at this link. I'm sure that you can find some good chances to listen German and also practice with people if you have anough guts to break the ice with whom is sitting next to you. Just ask how they are doing and if they would like to talk a couple of minutes in the break to help you out with German. I always do and sometimes people are very nice: if they are not, it's their loss and not yours ;)
Take also a look at whether there are table-top society (board games groups) in the city. They are usually very open and playing a game is a good chance to have something to speak about.
https://www.facebook.com/FreisingerSpieletreff/ This looks quite ok, perhaps try to message them on facebook =)
This is what comes to my mind at the moment regarding offline meetings. Unfortunately I'm not living in Freising or we could meet and practice together. But I wish you super good luck with your research!!!!
Let me know auf jeden Fall - ;) - how it goes with your research and your practice!
Best wishes for a good time in Freising und viel Erfolg with German.
