My boyfriend of more than 2 years just left for basic training over a week ago. Will he get unwanted attention if I send him a lot of mail? Is there such thing as too much mail? So far I've written like 10 letters and will be sending them off today along with some pictures. Should I send the 10 letters separately or put them all together so it doesn't seem like I'm obsessive... What if I send one of those flat rate envelopes? Is there a limit to what size of envelope I can send? Do they receive mail everyday?
