I myself wouldn't want to summon anything I couldn't handle. That being said, summoning, unless you know what you are doing, can be dangerous as you are technically rudely dragging someone outta their home, in the middle of their business to come do something for you. I personally wouldn't be happy.
Also, no offense, but it seems like you are looking more for a girlfriend in this spirit, rather than an friendship. once again, no offense meant and it is quite likely I misread something somewheres. ;)
