Hortulus, hortuli

Assuming you have drawn the coffee cup, I now need you to answer these three questions:

On which side did you draw the handle?

Are you right-handed or left-handed?

Do you primarily write using the Latin alphabet or a different one? (please specify which)

More context

Most people will draw the handle on the right side. My professor says it's because most people are right-handed, so they draw the handle in the direction that would be comfortable for them to pick up.

I said drawing it on the right side just felt more comfortable to my hand and argued it's probably because we write a bunch of letters like that. B, b, D, P, p, R all look like a tiny "handle on the right side" and are all a straight line followed by a round one (so "cup first, handle second," like most people draw cups). The Latin alphabet doesn't have letters like that that face the other way, except maybe d, depending on how you write it, so it makes sense to me that people writing mostly Latin letters would go with the handle on the right side.

Which means that I need to know what Asians, Arabs and Greeks do and if the distribution of left and right sides of handles differs from the Latin alphabet group. Cyrillic seems to favor right, too, though it'd be interesting to see if there are differences.

If there are, my theory is right. Doubly so if there is a sizeable increase in a group whose alphabet has letters that benefit the left side choice.

So feel free to spread this to as many people as you like and put the answers in the comments or the tags of a reblog. The more answers I get, the better I can assess whose theory is better.
