<human>: Can you summarize the given text in a few sentences?

So I look much older than I am and she looks much younger than she is.  I'm 6 feet tall, and I have a beard, and I'm a bit thick.  I probably have more wrinkles on my face than the average person my age, and my hairline is receding.  I also have a bit of chub around my belly.  The way I dress always makes me look much older, I always wear suits and have a tendency to wear overcoats and gloves over them when its cold.

My girlfriend on the other hand is 20 years old, but she looks far younger.  She's 4'10", has a pretty thin body and a flat chest, as well as a pretty young face.  Her attitude and personality can also be a bit child like at times, always cheery.

(Before anyone asks, I definitely know she's 20.  I've met her parents on multiple occasions, and I also happen to have seen her drivers license, and seen her drive.)

So my problem is that whenever we go out together, we always get strange looks.  The age difference between us appears to be almost generational from a physical standpoint, and I can see how someone could easily mistake her for a 14 year old. 

I always feel like I'm being judged when I'm in public, people are treating me like I'm some sort of paedophile.  On a few rare occasions, people have asked what we were doing together.  Like, random strangers walk up to us, with a friendly attitude and all, but you can tell they are doing it because they are suspicious.

When we go to restaurants or bars, she always gets asked for ID, and is often met with skepticism. (We're not in the states, so she can legally drink).

Yeah its become a real bother, though I'm not sure there's much I can do about it.
<bot>: Girlfriend and I, although only 3 years apart in age, look much further apart in age. I get weird looks in public.
