Welcome indeed Nwa Nsukka. May I ask which is your first name and which is your last name? Is your first name 'Nwa' and your surname 'Nsukka'?

. Nooo, I think you should travel a bit, don't because of your brother that has not returned from Germany and not travel. If you want I can recommend some places for you to travel to.
Maybe, someday, you're brother will join this community! Who knows one of these days he might just be searching for 'UNN' in google and this site will show up, who knows. I wish you all the best in the community and do be a good community member. Once again, I welcome you as one of the first arrivals.
Phronesis.
